Hastelloy C-276 round bar 2026 latest factory price commonly ranges from approximately USD 45 to 95 per kg for standard industrial hot-finished, forged, solution-annealed, or peeled round bars purchased in regular production quantities. Cold-drawn, precision-ground, large forged, tightly toleranced, specially inspected, or small-quantity Hastelloy C-276 round bars may cost approximately USD 65 to 135 per kg or more. Hastelloy C-276, also known as Alloy C-276, UNS N10276, and W.Nr. 2.4819, is a nickel-molybdenum-chromium-tungsten alloy widely used in chemical processing, flue gas desulfurization, pollution control, pulp and paper, waste treatment, acid equipment, seawater-related systems, valves, pumps, shafts, fasteners, and corrosion-critical machined parts. The final factory price in 2026 depends on nickel, molybdenum, chromium, and tungsten costs, diameter, manufacturing route, solution-annealed condition, surface finish, tolerance, testing, certification, MOQ, stock status, lead time, and delivery terms.
Hastelloy C-276 round bar is one of the most widely recognized corrosion-resistant nickel alloy bar products. It is selected when ordinary stainless steel, duplex stainless steel, Alloy 400, Inconel 600, or even some common nickel alloys cannot provide enough resistance to mixed chemical environments, chlorides, pitting, crevice corrosion, wet chlorine, oxidizing salts, reducing acids, and contaminated process streams.
The 2026 factory price of Hastelloy C-276 round bar should not be judged only by one online listing. C-276 contains high-value alloying elements, especially nickel, molybdenum, chromium, and tungsten. It also requires controlled melting, forging or rolling, solution annealing, straightening, peeling or grinding, inspection, testing, and traceability. A factory quotation normally reflects all of these production and quality-control costs.
Factory price usually means the material price offered by a mill, forging factory, rolling plant, or integrated nickel alloy processor before international freight, insurance, import duties, taxes, anti-dumping duties, customs clearance, destination delivery, and local distributor margins. In export business, it is often quoted on an EXW or FOB basis unless the buyer requests CIF, DAP, or DDP terms.

The direct answer is that standard Hastelloy C-276 round bar in 2026 commonly costs approximately USD 45 to 95 per kg at factory level. This range is most suitable for regular industrial orders involving common diameters, commercial tolerances, solution-annealed condition, standard MTC, and normal lead time.
For small-diameter cold-drawn bars, large forged bars, precision-ground bars, tight straightness requirements, many fixed-length cut pieces, special surface finish, ultrasonic testing, corrosion testing, third-party inspection, or small-quantity orders, the price may rise to approximately USD 65 to 135 per kg or more.
| Purchasing Requirement | 2026 Budgetary Price | Commercial Explanation |
|---|---|---|
| Standard full-length factory bar | USD 45–85/kg | Common diameter, factory MOQ, standard MTC, commercial tolerance |
| Peeled or turned round bar | USD 50–95/kg | Scale removed, better surface, less machining allowance |
| Fixed-length cut pieces | USD 55–105/kg | Includes cutting, kerf loss, marking, inspection, and repacking |
| Large forged bar | USD 60–120/kg | Includes forging, annealing, rough turning, and possible UT |
| Precision-ground bar | USD 75–135/kg | Includes peeling, straightening, grinding, and dimensional inspection |
| Small sample or urgent order | Supplier-specific premium | Setup, cutting, certification, and packing costs are divided over fewer kilograms |
Online listings may show a very low price for one size, one stock lot, one minimum quantity, or one market region. Some prices refer to old inventory, offcuts, semi-finished material, or products without the same certificate and testing scope. A serious purchasing comparison should confirm grade, standard, diameter, length, condition, surface finish, tolerance, inspection scope, available quantity, quotation validity, and delivery term.
A low price is not useful if the bar does not meet ASTM B574, ASME SB574, customer specification, chemical requirements, solution-annealed condition, or heat-number traceability. For chemical equipment and pressure-related parts, certificate quality and alloy identity are as important as the price per kilogram.
Hastelloy C-276 is commonly identified as UNS N10276 and W.Nr. 2.4819. It may also be described as Alloy C-276, Nickel Alloy C-276, NiMo16Cr15W, NC17D, or nickel-molybdenum-chromium-tungsten alloy. UNS N10276 should appear on the quotation, purchase order, material test certificate, product marking, packing label, and inspection documents.
Correct grade identification is important because C-276 can be confused with C-22, B-3, Inconel 625, Alloy 59, or other corrosion-resistant nickel alloys. These grades may look similar in supplier catalogs, but they have different chromium, molybdenum, tungsten, iron, corrosion resistance, availability, and price levels.

Hastelloy C-276 is a nickel-molybdenum-chromium-tungsten alloy with very low carbon and silicon. Nickel forms the alloy base. Molybdenum provides strong resistance to reducing conditions, pitting, and crevice corrosion. Chromium contributes resistance to oxidizing media. Tungsten improves resistance in severe localized corrosion environments.
The low carbon and silicon levels are important because they help reduce the risk of harmful grain-boundary precipitates in the weld heat-affected zone. This is one reason C-276 is widely used for welded chemical-processing equipment.
| Element | Specified Range or Limit | Main Function or Control Reason |
|---|---|---|
| Nickel | Balance | Provides the corrosion-resistant nickel-base matrix |
| Molybdenum | 15.0–17.0% | Improves resistance to reducing acids, pitting, and crevice corrosion |
| Chromium | 14.5–16.5% | Improves resistance to oxidizing chemicals and mixed environments |
| Iron | 4.0–7.0% | Controlled major constituent of the alloy balance |
| Tungsten | 3.0–4.5% | Improves localized corrosion resistance in severe environments |
| Cobalt | 2.5% maximum | Controlled residual or minor element |
| Manganese | 1.0% maximum | Controlled processing-related element |
| Vanadium | 0.35% maximum | Controlled residual element |
| Copper | 0.50% maximum | Controlled residual element |
| Carbon | 0.010% maximum | Kept very low to reduce carbide precipitation risk |
| Silicon | 0.08% maximum | Kept very low to support weld-area corrosion resistance |
| Phosphorus | 0.040% maximum | Controlled impurity |
| Sulfur | 0.030% maximum | Controlled impurity affecting hot workability and weld quality |
The material test certificate should show the actual heat analysis. Buyers should verify molybdenum, chromium, tungsten, iron, carbon, silicon, cobalt, sulfur, and phosphorus against the required standard.
PMI can help confirm major alloying elements such as nickel, molybdenum, chromium, tungsten, and iron. However, PMI does not replace laboratory heat analysis for carbon, silicon, sulfur, or phosphorus. The original MTC and heat-number traceability remain essential for corrosion-critical applications.
The 2026 factory price of Hastelloy C-276 is strongly influenced by nickel, molybdenum, chromium, and tungsten. Nickel provides the base matrix, while molybdenum and tungsten are high-value alloying elements. Chromium is essential for oxidizing corrosion resistance and contributes to the alloy surcharge.
Nickel is the largest base component by weight. Changes in LME nickel prices affect new production costs, alloy surcharges, replacement value, and quotation validity. However, finished C-276 round bar costs much more than the nickel content alone because it includes high-value alloying elements, melting, forging, rolling, annealing, surface processing, inspection, and factory overhead.
Molybdenum content is approximately 15% to 17%, which is much higher than in Inconel 625 and many other nickel alloys. Molybdenum is a major reason C-276 costs more than simpler nickel-chromium alloys such as Inconel 600 or 601.
When molybdenum prices rise, C-276 factory prices can increase even if nickel prices remain stable. This is why 2026 quotations may have short validity periods.
Chromium content is approximately 14.5% to 16.5%. Chromium helps C-276 resist oxidizing chemicals and mixed acid environments. It is not usually the most expensive element in the alloy, but it is a significant part of the total alloy cost.
Tungsten content is approximately 3.0% to 4.5%. Although lower in percentage than nickel or molybdenum, tungsten is a high-value element and contributes to the price premium of C-276 compared with some molybdenum-containing nickel alloys.
| Element | Typical Content | Relative Cost Influence | Main Performance Contribution |
|---|---|---|---|
| Nickel | Balance | Very high | Base matrix, corrosion resistance, ductility, and stability |
| Molybdenum | 15–17% | Very high | Reducing acid resistance, pitting resistance, and crevice corrosion resistance |
| Chromium | 14.5–16.5% | Medium to high | Resistance to oxidizing chemicals and mixed corrosion environments |
| Tungsten | 3.0–4.5% | High | Improves resistance to localized corrosion in severe media |
Diameter has a direct effect on C-276 round bar factory price. Medium diameters are usually the most economical because they are more commonly produced and easier to stock. Small rods require additional drawing and finishing. Large diameters often require forging, solution annealing, rough machining, and ultrasonic testing.
| Diameter Range | Factory Price Reference | Typical Manufacturing Route |
|---|---|---|
| 3–10 mm | USD 80–140/kg | Cold drawn, straightened, polished, or precision ground |
| 12–20 mm | USD 65–120/kg | Cold drawn, peeled, small hot-finished, or ground bar |
| 22–80 mm | USD 45–95/kg | Common hot-finished, forged, solution-annealed, or peeled bar |
| 85–150 mm | USD 55–110/kg | Forged, annealed, peeled, or rough-turned bar |
| 160–250 mm | USD 65–130/kg | Custom forged, solution annealed, rough machined, and often UT-tested |
| Above 250 mm | Custom factory quotation | Project-specific billet, forging, heat treatment, machining, and inspection |
| Diameter | Approximate Weight per Meter | Purchasing Meaning |
|---|---|---|
| 20 mm | About 2.79 kg/m | Low total weight, but small-diameter processing can increase price per kg |
| 50 mm | About 17.45 kg/m | Common machining diameter with relatively stable pricing |
| 100 mm | About 69.8 kg/m | Higher total order value and heavier cutting requirements |
| 200 mm | About 279 kg/m | Usually forged and may require UT, lifting, and special packing |
The weights above are approximate and calculated using a nominal density of about 8.89 g/cm³. Actual invoice weight should be based on measured dimensions or scale weight.
Small-diameter C-276 bars often have a higher price per kilogram because they require more processing per kilogram of finished material. Large-diameter bars also cost more, but the main reasons are forging difficulty, heat treatment, inspection, and handling.
| Small-Bar Cost Factor | Effect on Factory Price |
|---|---|
| Cold-drawing passes | Add tooling, lubrication, machine time, and process control |
| Intermediate annealing | May be required because nickel alloys work-harden during cold reduction |
| Surface cleaning | Required between drawing and finishing operations |
| Precision straightening | Adds processing time and dimensional inspection |
| Centerless grinding | Adds finishing cost and reduces saleable material yield |
| Small batch quantity | Spreads setup, furnace, testing, and documentation costs over fewer kilograms |
| Large-Bar Cost Factor | Effect on Factory Price |
|---|---|
| Large billet or ingot | Raises raw material commitment and factory MOQ |
| Multiple forging heats | Add press time, furnace energy, labor, and process risk |
| Long solution-annealing cycle | Requires full-section heating and controlled cooling |
| Rough turning | Removes scale and surface imperfections but reduces finished yield |
| Ultrasonic testing | Adds internal-quality inspection cost and possible rejection risk |
| Heavy handling and packing | Requires lifting equipment, stronger packing, and special transport control |
Round bars from approximately 22 mm to 80 mm often provide the best balance of price, availability, machining allowance, and delivery time. The exact economical range depends on factory equipment, existing billet stock, and current production schedule.
The manufacturing route is one of the clearest reasons why two Hastelloy C-276 quotations differ. A hot-finished black bar and a precision-ground h7 bar are not equivalent products even when they have the same nominal diameter.
Hot-finished bar is usually the most economical choice for general machining blanks. It normally has wider mill tolerance and more surface scale than peeled or ground material. Buyers should allow enough machining stock to remove surface scale and reach the final dimension.
Forged bar is used for large diameters, heavy shafts, valve bodies, pump components, pressure parts, and custom machining blanks. Forging cost depends on billet size, forging ratio, number of reheats, solution annealing, rough turning, UT requirements, and final dimensions.
Cold-drawn bar provides better diameter tolerance, surface finish, straightness, and mechanical strength for small diameters. Cold drawing may require intermediate annealing and final solution annealing depending on reduction ratio and delivery condition.
Precision-ground bar is used for pump shafts, valve stems, fastener blanks, instrument rods, pins, and corrosion-resistant precision parts. It costs more because it requires peeling, straightening, centerless grinding, dimensional inspection, and protective packing.
| Bar Condition | 2026 Factory Price Reference | Main Advantage | Main Cost Addition |
|---|---|---|---|
| Hot finished | USD 45–78/kg | Economical general machining blank | Standard tolerance and limited finishing |
| Forged | USD 58–115/kg | Large diameter and heavy-section capability | Forging, reheating, annealing, rough turning, and UT |
| Cold drawn | USD 65–120/kg | Improved tolerance, surface, and straightness | Drawing stages, annealing, and inspection |
| Peeled or turned | USD 50–95/kg | Cleaner surface and reduced machining allowance | Surface removal and dimensional control |
| Precision ground | USD 75–135/kg | Tight diameter and smooth finished surface | Grinding, straightening, inspection, and protective packing |
Hastelloy C-276 is generally supplied in the solution-annealed condition for optimum corrosion resistance and fabricability. It is a solid-solution-strengthened alloy, not a precipitation-hardening alloy like Inconel 718 or Inconel X-750.
Solution annealing helps restore the desired microstructure after hot working or cold working. It reduces the risk of harmful precipitates and supports corrosion resistance in aggressive environments. For corrosion-critical chemical equipment, the delivery condition should be clearly stated on the purchase order and MTC.
Forged or hot-finished C-276 bar typically requires final solution annealing before supply. Large bars take longer to heat through the full section and may require more furnace time. This increases the factory cost compared with smaller standard bars.
Cold-drawn or heavily worked material may need intermediate annealing and final solution annealing. Additional annealing cycles increase furnace cost, handling, straightening, and testing time.
| Heat Treatment Requirement | Purpose | Factory Cost Effect |
|---|---|---|
| Standard solution annealing | Provides normal corrosion resistance and ductility | Usually included in compliant mill production |
| Re-annealing after forging | Restores optimum structure after hot working | Adds furnace, handling, and inspection cost |
| Intermediate annealing during drawing | Restores ductility between cold-reduction stages | Can add several furnace and handling cycles |
| Final annealing after cold work | Restores corrosion resistance and dimensional stability | Adds furnace cost and may require final straightening |
| Customer-specific thermal cycle | Meets a project-defined metallurgical requirement | Project-specific and may require qualification |
For C-276, incorrect or undocumented heat treatment may reduce corrosion performance. A lower-priced bar with unclear thermal history may not be suitable for chemical processing equipment, pressure components, welded assemblies, or critical acid service.
Stock or regularly produced C-276 sizes usually offer lower prices and shorter lead times than custom production. C-276 is more commonly stocked than Hastelloy B-3, but special diameters, large forged sections, or precision-ground sizes may still require new production.
Ready stock can reduce MOQ, setup cost, lead time, and raw material price exposure. Buyers may obtain a lower total cost by choosing a slightly larger stock diameter and machining it down to the required final size.
Custom production may involve billet allocation, forging, rolling, drawing, solution annealing, rough turning, peeling, grinding, UT, testing, and certificate preparation. The factory may calculate price based on gross production weight rather than the buyer’s final usable weight.
| Comparison Item | Stock or Regular Size | Custom Size |
|---|---|---|
| Price per kg | Usually lower | Usually higher |
| MOQ | May allow one full bar or available cut pieces | May require a full rolling, forging, or drawing batch |
| Lead time | Shorter after certificate approval | Longer because of production and inspection |
| Dimensional flexibility | Limited to inventory | Can be produced closer to the machining size |
| Manufacturing yield | Generally more efficient | May involve higher end loss, scale, and setup scrap |
| Certification flexibility | Limited to original stock documentation | Can be planned for a project-specific standard |
A custom near-net-size bar may cost more per kg but reduce machining time, tool wear, and alloy scrap. This matters especially for large C-276 components because the material is dense and expensive. Buyers should compare gross bar weight, cutting loss, machining allowance, scrap recovery, and finished-part yield.
Surface condition, diameter tolerance, roundness, ovality, straightness, and surface roughness can add a major premium to the base C-276 factory price. Buyers should define these requirements numerically rather than using vague terms such as “bright,” “smooth,” or “high precision.”
| Surface Condition | Typical Characteristics | Relative Cost |
|---|---|---|
| Hot-finished black surface | Scale present and machining allowance required | Lowest |
| Descaled or pickled | Scale removed for inspection or fabrication | Low to medium |
| Peeled or rough turned | Clean metallic surface and improved diameter control | Medium |
| Polished | Improved appearance and surface smoothness | Medium to high |
| Precision ground | Tight diameter, roundness, straightness, and roughness control | Highest |
Standard ASTM or commercial mill tolerance is normally the lowest-cost option. Tighter tolerances such as h11, h9, h8, h7, or customer-specific ground tolerance require extra material allowance, machining, grinding, inspection, and rejection control.
Long pump shafts, valve stems, rods, and rotating components may require strict straightness per meter. Heat treatment and grinding can affect straightness, so straightening may be required after solution annealing and again after final grinding.
Precision components may require numerical roundness, ovality, and Ra values. If these values are not defined, suppliers may quote standard commercial surface only, which may not meet the buyer’s final machining or assembly needs.
| Dimensional Requirement | Lower-Cost Option | Higher-Cost Option |
|---|---|---|
| Diameter | Standard mill tolerance | h9, h8, h7, or drawing-specific ground tolerance |
| Straightness | Commercial straightness | Strict deviation per meter with inspection report |
| Roundness | Hot-finished or peeled condition | Precision-ground roundness requirement |
| Surface roughness | Commercial peeled surface | Specified Ra after grinding or polishing |
| Surface defects | Commercially acceptable imperfections | Fully machined or defect-free surface requirement |
The base factory price may not include cutting, machining, special testing, or expanded certification. Buyers should request an itemized quotation when the order includes fixed-length blanks, rough machining, PMI, UT, corrosion testing, or third-party inspection.
Saw cutting includes machine time, blade wear, kerf loss, length measurement, deburring, heat-number transfer, inspection, and repacking. Many short pieces usually have a higher effective price per kg than one full-length bar.
Hastelloy C-276 work-hardens during machining and has lower thermal conductivity than many steels. Machining requires rigid equipment, sharp tooling, stable feed, controlled cutting speed, and effective coolant. Slow machining rates and high tool consumption can raise the cost of turned, drilled, threaded, or finished components.
Standard factory supply normally includes an MTC with heat analysis and required mechanical properties. Additional testing may include PMI, independent laboratory chemistry, UT, hardness testing, tensile testing, macrostructure inspection, grain-size evaluation, corrosion testing, ferric chloride pitting test, or third-party witnessing.
EN 10204 3.1 certification is common for industrial orders. EN 10204 3.2 certification, customer witnessing, independent inspection, manufacturing procedure records, and project-specific document packages add cost and delivery time.
| Additional Service | Typical Cost Effect | Main Cost Reason |
|---|---|---|
| Single saw cut | Low | Basic machine time, blade wear, and measurement |
| Many fixed-length pieces | Medium | Repeated cutting, marking, inspection, and individual packing |
| Rough turning | Medium | Machine time, tool wear, and material removal |
| Precision machining | High | Slow cutting rates, work hardening, and tight tolerance |
| PMI testing | Low to medium | Major alloying-element verification and test reporting |
| Ultrasonic testing | Medium to high | Internal-quality examination, calibration, and reporting |
| Corrosion testing | High | Laboratory preparation, controlled exposure, and reporting |
| Third-party inspection | Medium to high | Inspector fees, coordination, witnessing, and document review |
| EN 10204 3.2 certification | High | Independent validation and expanded documentation |
The MTC should identify UNS N10276, applicable standard, heat number, actual chemistry, product dimensions, delivery condition, and required mechanical properties. The heat number on the certificate should match the product marking and packing label.
When a full bar is cut into several pieces, identification should be transferred to every piece or maintained through an approved traceability system. This is especially important for chemical equipment, pressure parts, and project-controlled procurement.
Order quantity has a strong influence on the 2026 factory price of Hastelloy C-276 round bar. The factory must consider billet size, forging or rolling campaign, heat-treatment furnace load, testing lot, process yield, and production scheduling.
Regular batch orders usually receive better pricing because setup, annealing, inspection, certification, and packing costs are distributed over more kilograms. Small sample orders or many short pieces carry higher unit costs.
A large order does not always guarantee a lower immediate price if it requires new production during a period of rising molybdenum, tungsten, or nickel costs. Existing stock and new production may have different cost bases.
MOQ depends on diameter and production route. A common stock bar may be sold by the full length or cut piece. A custom forged diameter may require a full billet. A special cold-drawn diameter may require a drawing batch and intermediate annealing cycles.
| Supply Situation | MOQ Direction | Commercial Effect |
|---|---|---|
| Available full bar | One bar or supplier-defined minimum | Shorter lead time and limited setup cost |
| Regular factory diameter | Moderate production quantity | Better production efficiency and unit price |
| Custom cold-drawn diameter | Drawing-batch quantity | Tooling, annealing, and setup raise cost |
| Large custom forging | Based on full billet input weight | Gross production weight can exceed final ordered weight |
| Special testing or certification lot | May require a dedicated production batch | Laboratory, segregation, and documentation costs increase |
Ready stock or available semi-finished billet can shorten delivery. New production may involve raw material procurement, melting, billet preparation, forging or rolling, solution annealing, straightening, surface processing, UT, laboratory testing, certificate approval, and packing.
Urgent delivery may require priority production, subcontracted machining, expedited testing, or air freight. In some export orders, logistics and inspection delays can affect the final delivered cost more than the difference between two base factory prices.
Nickel, molybdenum, chromium, and tungsten prices remain important in 2026. Nickel affects the base matrix cost. Molybdenum and tungsten strongly affect C-276 alloy surcharge. Chromium affects both corrosion performance and raw material value.
Because raw material markets can change quickly, many factories issue quotations with limited validity. A quote valid for 3 to 7 days may be more common during volatile periods. A long fixed-price validity may include a risk premium.
| Price Factor | More Economical Situation | Higher-Cost Situation |
|---|---|---|
| Quantity | Full bars or regular production batch | Sample, prototype, or many small cut pieces |
| MOQ | Suitable billet or bar is available | Dedicated forging, rolling, or drawing batch required |
| Lead time | Normal factory schedule | Priority production and expedited shipment |
| Raw material market | Stable nickel, molybdenum, and tungsten prices | Rapidly rising or volatile alloying-element markets |
| Price validity | Short validity based on current costs | Long fixed validity requiring supplier risk coverage |
Hastelloy C-276, C-22, B-3, and Inconel 625 are all premium corrosion-resistant nickel alloys, but they are designed for different chemical environments. Their prices can overlap depending on size, origin, stock, and certification.
| Alloy | Budgetary Standard Bar Price | Main Cost Reason | Main Application Direction |
|---|---|---|---|
| Inconel 625 | Approximately USD 30–65/kg | High nickel, chromium, molybdenum, and niobium content | Seawater, offshore, chloride pitting, crevice corrosion, and general corrosion service |
| Hastelloy C-276 | Approximately USD 45–95/kg | Nickel, molybdenum, chromium, and tungsten composition | Broad chemical resistance in oxidizing and reducing environments |
| Hastelloy C-22 | Approximately USD 55–110/kg | Higher chromium and strong Ni-Cr-Mo corrosion alloy positioning | Oxidizing chlorides, mixed acids, and severe chemical process streams |
| Hastelloy B-3 | Approximately USD 55–110/kg | Very high molybdenum and high nickel content with limited production volume | Hydrochloric acid and strongly reducing chemical environments |
C-22 often costs slightly more than C-276 because of its alloy design, high chromium content, and strong performance in oxidizing chloride environments. However, the actual price can overlap if C-276 is available only by custom production while C-22 is available from stock, or vice versa.
C-276 is widely used because it provides a balanced combination of reducing-acid resistance, oxidizing resistance, chloride resistance, weldability, and fabricability. C-22 may be selected where oxidizing chlorides or certain mixed acid streams require stronger chromium-rich corrosion resistance.
B-3 contains much higher molybdenum and is often expensive, but its application range is narrower. It is mainly selected for strongly reducing environments such as hydrochloric acid where oxidizing contaminants are controlled.
C-276 is usually more versatile because it contains chromium and tungsten as well as molybdenum. It can handle a wider range of mixed oxidizing and reducing environments. In many chemical plants, this broader corrosion resistance justifies its factory price.
Inconel 625 is normally cheaper and more widely stocked. It is a good choice for seawater, offshore, chlorides, and many general corrosion applications. C-276 costs more because it contains tungsten and more molybdenum and is designed for more severe chemical corrosion environments.
When the service involves wet chlorine, hypochlorites, ferric chloride, mixed acids, severe pitting, or aggressive chemical process streams, C-276 may justify the higher price. When seawater and general chloride corrosion are the main concerns, Inconel 625 may offer better cost efficiency.
Material selection should not be based only on price. The buyer should evaluate acid type, concentration, temperature, pressure, oxidizing impurities, chlorides, dissolved oxygen, pH, flow rate, crevice conditions, welding requirements, cleaning procedure, shutdown condition, and expected service life.
For critical equipment, a corrosion test or specialist material review may prevent costly failure. Saving money on the initial bar price can be expensive if the alloy is not suitable for the real chemical stream.
How much is Hastelloy C-276 round bar per kg in 2026?
Standard industrial Hastelloy C-276 round bar commonly costs approximately USD 45 to 95 per kg at factory level in 2026. Forged, cold-drawn, precision-ground, tightly toleranced, specially tested, small-quantity, or custom-size bars may cost approximately USD 65 to 135 per kg or more. Final pricing depends on diameter, quantity, manufacturing route, solution-annealed condition, surface finish, tolerance, inspection, MOQ, raw material prices, and delivery terms.
Why is Hastelloy C-276 round bar more expensive than Inconel 625?
Hastelloy C-276 usually costs more than Inconel 625 because it contains higher molybdenum and also includes tungsten. These elements improve resistance to severe chemical corrosion, pitting, crevice corrosion, and mixed oxidizing and reducing environments. C-276 is also more specialized than Inconel 625 in many markets, so stock availability, production volume, and testing requirements can further increase the factory price.
What information is needed to get an accurate Hastelloy C-276 factory price?
To obtain an accurate quotation, provide grade, UNS number, standard, diameter, length, quantity, delivery condition, surface finish, tolerance, cutting requirement, testing requirement, certificate type, destination, and Incoterm. A complete RFQ such as “Hastelloy C-276 round bar, UNS N10276, ASTM B574, diameter 50 mm, length 3000 mm, quantity 500 kg, solution annealed and peeled, with EN 10204 3.1 MTC” allows the factory to check stock, calculate weight, confirm processing cost, and quote more accurately.
