Hastelloy G-30 N06030 bar factory price is determined by the alloy’s high nickel, chromium, iron, molybdenum, copper, and tungsten content, together with the requested bar dimensions, manufacturing route, surface condition, testing, documentation, and shipment terms. G-30 is a specialized corrosion-resistant nickel alloy, so a meaningful price per kilogram can only be calculated after the buyer defines the exact material grade, standard, bar form, diameter, length, tolerance, heat-treatment condition, quantity, and destination. Comparing quotations without matching these details can lead to an inaccurate purchasing decision.
Hastelloy G-30 alloy bar is used in severe corrosive environments, particularly where wet-process phosphoric acid, nitric acid, oxidizing acids, fluoride-bearing media, chlorides, or mixed chemical streams are present. Its chemistry is designed to provide a strong balance of resistance to general corrosion, pitting, crevice corrosion, and stress corrosion cracking in selected process environments.
For this reason, G-30 bars are frequently purchased for chemical processing equipment, fertilizer plants, phosphoric acid systems, nitric acid units, pollution-control systems, pickling equipment, heat exchangers, pumps, valves, fasteners, shafts, agitators, fittings, and custom machined components. The factory price is influenced not only by metal market changes but also by the quality requirements needed for these high-value service applications.
Hastelloy is a registered trademark. For purchasing and technical documentation, the correct material designation should include UNS N06030. Some market searches may contain an incorrect letter-number combination, but N06030 is the recognized UNS designation for Hastelloy G-30 alloy.
Hastelloy G-30 is a nickel-chromium-iron alloy with molybdenum, copper, and tungsten additions. It was developed to provide excellent resistance to highly oxidizing acid environments while maintaining useful resistance in chloride-containing conditions. Compared with standard stainless steels and many common nickel alloys, G-30 offers a higher-performance solution for difficult chemical processing duties.
Hastelloy G-30 N06030 bar can be supplied as round bar, forged bar, hot-rolled bar, cold-drawn bar, bright bar, flat bar, square bar, hex bar, or cut-length machining stock. The selected form should suit the final manufacturing method. A large pump shaft may require forged round bar, while a precision valve stem may benefit from cold-drawn or ground bright bar with closer tolerance and improved straightness.

The corrosion performance of Hastelloy G-30 is closely related to its carefully balanced chemistry. Nickel provides the corrosion-resistant base structure, while the high chromium content supports resistance in oxidizing chemical environments. Molybdenum contributes to corrosion resistance in reducing and chloride-containing media. Copper, tungsten, and other controlled elements help create the alloy’s specialized performance profile.
The final chemical composition must be confirmed by the applicable material standard and the heat-specific mill test certificate. The following table is a general reference for quotation and purchasing communication.
| Element | Typical Range or Limit, wt.% | Role in the Alloy |
|---|---|---|
| Nickel | Balance | Provides the base corrosion-resistant matrix. |
| Chromium | 28.0-31.5% | Improves resistance to oxidizing acids and aggressive chemical media. |
| Iron | 13.0-17.0% | Controlled alloying element within the specified chemistry range. |
| Molybdenum | 4.0-6.0% | Supports resistance to reducing acids and localized chloride attack. |
| Copper | 1.0-2.4% | Improves performance in selected acid environments. |
| Tungsten | 1.5-4.0% | Contributes to the alloy’s corrosion-resistance balance. |
| Niobium plus tantalum | 0.3-1.5% | Controlled alloying addition for metallurgical performance. |
| Cobalt | 5.0% maximum | Restricted as part of controlled alloy chemistry. |
| Carbon | 0.03% maximum | Low carbon supports corrosion-resistant fabrication performance. |
Hastelloy G-30 bars are commonly supplied in annealed or solution-annealed condition, depending on the applicable product specification and customer requirement. Buyers should specify any required tensile properties, hardness range, grain-size control, heat-treatment condition, or corrosion-testing requirement before production. The correct delivery condition is especially important for components that will be welded, machined, or exposed to stress-corrosion service.
Hastelloy G-30 is particularly known for its strong resistance to wet-process phosphoric acid. This makes it a valuable material option for phosphoric acid production, fertilizer processing, evaporators, reactors, heat exchangers, pumps, valves, fittings, and mechanical components that operate in phosphoric acid streams containing impurities.
The high chromium content of G-30 provides strong resistance to oxidizing acids, including nitric acid service within suitable concentration and temperature limits. In chemical plants, oxidizing environments can create corrosion mechanisms that are not adequately controlled by alloys optimized only for reducing acid resistance. G-30 offers a useful solution where oxidizing conditions are a central part of the process.
Chlorides can create pitting and crevice corrosion, especially in stagnant zones, beneath deposits, under gaskets, around threaded connections, or in poorly drained equipment. The nickel, chromium, molybdenum, and tungsten balance of Hastelloy G-30 helps resist localized corrosion in low-to-moderate chloride conditions. Actual alloy selection should still be based on the real process chemistry, temperature, chloride concentration, flow condition, and risk of crevice formation.
Compared with many stainless steels, Hastelloy G-30 offers better resistance to chloride-induced stress corrosion cracking in suitable environments. This can be important for bars machined into shafts, bolts, valve stems, and load-bearing parts that experience both tensile stress and corrosive exposure. Cold work and final fabrication methods should be considered because they can affect stress-corrosion performance.
| Corrosion Challenge | Why G-30 May Be Selected |
|---|---|
| Wet-process phosphoric acid | Provides high resistance in demanding phosphoric acid service. |
| Oxidizing acids | High chromium content supports performance in oxidizing media. |
| Nitric acid environments | Often considered for selected nitric acid processing duties. |
| Chloride-bearing streams | Helps resist pitting and crevice corrosion in appropriate conditions. |
| Mixed chemical process streams | Useful where both oxidizing and reducing corrosion influences are present. |
| Stress corrosion concerns | Offers improved resistance compared with many common stainless steels. |
The term “Hastelloy G-30 bar” can refer to several different forms with different manufacturing routes and cost structures. Round bar is most common for shafts, pins, valve components, bolts, nuts, and machined parts. Flat, square, and hex bars may be used for brackets, fittings, fasteners, blocks, and custom-machined components.
| Product Form | Typical Use | Commercial Consideration |
|---|---|---|
| Hot-rolled round bar | General machining and standard industrial components | Usually efficient for common diameters and normal machining allowance. |
| Forged round bar | Large pump parts, shafts, and critical machined components | May require a higher conversion cost and longer lead time. |
| Cold-drawn round bar | Precision shafts, small pins, and close-tolerance parts | Added dimensional processing can increase price per kilogram. |
| Peeled or turned bar | Machined parts requiring improved surface condition | Includes additional processing and metal removal. |
| Ground and polished bar | Close-tolerance precision components | Typically priced higher due to finishing and inspection work. |
| Flat, square, or hex bar | Fasteners, fittings, and custom engineering parts | Availability may be more limited than standard round bar. |
To receive a correct quote, the inquiry should state the bar shape, nominal dimension, required tolerance, length, delivery condition, quantity, and whether random mill length is acceptable. A simple request for “G-30 bar” leaves too many technical variables open and can lead to quotations that are difficult to compare.
Hastelloy G-30 bar manufacturing requires controlled alloy production because the final corrosion resistance depends on precise chemistry, metallurgical condition, and surface quality. The process generally includes melting, chemistry analysis, ingot or billet conversion, hot working, heat treatment, finishing, inspection, marking, and packing.
The manufacturer begins with carefully controlled raw materials. Nickel, chromium, molybdenum, copper, tungsten, iron, and other alloying elements are melted and analyzed to ensure compliance with the specified chemical composition. Heat-number traceability should be maintained throughout manufacturing so the final test certificate can be matched to the delivered bars.
The cast alloy is converted into bar through forging, rolling, or a combination of hot-working processes. Large diameters often require forging, while standard sizes may be hot rolled. Proper temperature control and reduction practice are important to create a sound structure suitable for corrosion-resistant service and subsequent machining.
After hot working, the material may be annealed or solution annealed according to the required condition. The bar can then be supplied with black hot-rolled surface, peeled surface, turned surface, bright drawn surface, ground surface, or polished surface. Each additional finishing operation affects cost, lead time, and final dimensional capability.
Inspection may include chemical analysis, tensile testing, hardness testing, dimensional measurement, visual inspection, positive material identification, ultrasonic testing, liquid penetrant testing, and third-party inspection where required. Critical chemical-process components may require more documentation and inspection than standard commercial orders.
Hastelloy G-30 bar factory price is not determined by alloy weight alone. The price reflects the cost of nickel-based alloy raw materials, melting, hot working, heat treatment, dimensional processing, inspection, packing, and logistics. The buyer should compare quotations only after ensuring that the technical scope is the same.
| Pricing Factor | Effect on Factory Price |
|---|---|
| Nickel market movement | Directly affects the main raw-material cost base. |
| Chromium, molybdenum, copper, and tungsten cost | Influences alloy surcharge and total melting cost. |
| Bar diameter and form | Determines whether hot rolling, forging, drawing, or grinding is required. |
| Length and cut-to-length requirement | Special lengths add cutting, handling, inspection, and yield-loss cost. |
| Surface finish | Bright, peeled, turned, or ground bars cost more than black hot-rolled bars. |
| Dimensional tolerance | Tighter diameter, straightness, and ovality requirements increase processing cost. |
| Testing and documentation | PMI, UT, third-party inspection, and special reports add cost and lead time. |
| Order quantity | Larger orders may reduce unit cost by improving production efficiency. |
| Delivery term | EXW, FOB, CIF, DAP, and DDP quotations include different logistics scopes. |
Nickel is the principal cost reference for Hastelloy G-30 because it forms the base of the alloy. However, chromium, molybdenum, tungsten, copper, energy costs, exchange rates, freight, scrap availability, and production capacity also influence the actual factory price. A nickel market movement may affect new production quotations quickly, while existing stock can be priced based on the supplier’s earlier purchase cost and inventory policy.
For large or long-lead orders, buyers should ask whether the factory price is fixed for a specific validity period or linked to a metal surcharge formula. This is important when raw-material prices are moving, when delivery will be split into several batches, or when project approval may delay the purchase order.
The London Metal Exchange nickel price is a useful market indicator, but it is not the price of finished G-30 bar. The finished bar price includes melting, alloy additions, processing, heat treatment, testing, packing, financing, and delivery. A good quotation should show the currency, validity period, delivery term, and scope of included services.
Hot-rolled G-30 bar is commonly selected for standard dimensions and applications where the customer will perform machining after receipt. It normally provides an economical option for larger diameters, standard tolerances, and parts with sufficient machining allowance.
Cold-drawn G-30 bar is used where better dimensional control, straighter material, improved surface finish, or reduced machining allowance is important. Precision shafts, pins, valve components, fasteners, and instrument parts may benefit from cold-drawn or bright bar. The added drawing, straightening, and measuring operations generally result in a higher price per kilogram.
| Item | Hot-Rolled G-30 Bar | Cold-Drawn or Bright G-30 Bar |
|---|---|---|
| Typical finish | Black or mill finish | Bright, peeled, turned, or improved surface |
| Typical tolerance | Normal commercial tolerance | Closer diameter and straightness control |
| Machining allowance | Normally higher | Normally lower |
| Suitable use | General machining and larger components | Precision and close-tolerance components |
| Relative factory price | Usually lower for comparable weight | Usually higher due to added processing |
Diameter has a major effect on Hastelloy G-30 bar cost. Small-diameter bright bar may require multiple drawing passes, straightening, and close measurement. Large-diameter bar may require forging equipment, longer heat treatment, increased handling, and enhanced internal-quality inspection. Both extremes can carry a higher price per kilogram than standard stocked dimensions.
Length also affects cost. Random mill lengths are often more economical than fixed cut lengths. Special short lengths, narrow length tolerance, chamfered ends, individual tags, and protective packing all add production and handling work. If the buyer can accept random lengths and perform final cutting locally, the total purchasing cost may be reduced.
| Requirement | Potential Cost Impact |
|---|---|
| Small diameter with close tolerance | May require cold drawing, straightening, and additional dimensional inspection. |
| Large forged bar diameter | May require special forging capacity and longer heat-treatment cycles. |
| Random length | Usually more economical than many specified cut lengths. |
| Fixed cut length | Adds cutting, handling, inspection, and possible yield loss. |
| High straightness requirement | May require extra straightening and final verification. |
| Low ovality or ground finish | May require turning, peeling, or centerless grinding. |
There is no single fixed Hastelloy G-30 N06030 bar price per kilogram that applies to all orders. A reliable rate must be based on the exact product specification. A basic hot-rolled bar in a standard size may have a very different unit price from a solution-annealed, ground, close-tolerance bar supplied with third-party inspection and export packing.
Buyers should also confirm whether the quoted unit weight is based on theoretical weight, actual net weight, or finished piece weight. For cut-length orders, the difference between ordered weight and shipped weight should be clearly understood. The quotation should state the currency and whether taxes, packing, inland transportation, ocean freight, insurance, and destination charges are included.

Factory-direct purchasing can be a strong option for large quantities, non-standard sizes, special tolerances, custom machining allowance, project documentation, and repeat demand. Direct communication with the manufacturer can make it easier to confirm material source, manufacturing route, heat treatment, inspection plan, packing, and delivery schedule.
A trader or distributor can be the better option for small orders, urgent stock requirements, mixed-material purchases, or common sizes that are already available locally. The buyer should verify whether the supplier is the original producer, a processor, a stockholder, or a trading company. Each route can be suitable, but the material origin and traceability must be transparent.
| Supply Route | Best Suited For | Key Points to Check |
|---|---|---|
| Factory direct | Large projects, special sizes, custom requirements | MOQ, production schedule, quality plan, technical communication, and export terms. |
| Distributor | Urgent demand and standard stock sizes | Actual stock, heat number, material certificate, storage condition, and cut charges. |
| Trader | Small quantity or mixed-material procurement | Original material source, document authenticity, inspection scope, and delivery responsibility. |
For corrosion-resistant nickel alloy bar, inspection documents are an important part of the purchase. A mill test certificate should identify the heat number, chemical analysis, applicable specification, material condition, dimensions, and relevant mechanical test results. The certificate must remain traceable to the physical bar or bundle delivered to the customer.
More demanding projects may require positive material identification, ultrasonic testing, liquid penetrant testing, hardness testing, dimensional inspection reports, corrosion testing, customer witness inspection, or third-party inspection. These requirements add cost and lead time, but they can be necessary for chemical plants, fertilizer production, critical pumps and valves, pressure equipment, and controlled engineering projects.
| Test or Document | Purpose | When Commonly Requested |
|---|---|---|
| EN 10204 3.1 mill test certificate | Provides heat-traceable chemical and material test data. | Standard industrial and export orders. |
| Positive material identification | Confirms the alloy chemistry of the supplied material. | Critical maintenance and mixed-material projects. |
| Ultrasonic testing | Checks for internal discontinuities where specified. | Large-diameter or critical rotating components. |
| Liquid penetrant testing | Checks for surface-breaking defects. | Forged, machined, or high-integrity parts. |
| Third-party inspection | Provides independent verification of material and documents. | Major engineering and client-controlled procurement projects. |
| Dimensional inspection report | Confirms diameter, length, straightness, and tolerance. | Precision bar, shafts, and drawing-controlled components. |
An accurate Hastelloy G-30 bar quotation starts with a complete request for quotation. A manufacturer can calculate the correct price and lead time only when the alloy grade, standard, bar form, dimensions, tolerance, quantity, condition, testing, packing, and delivery term are known.
