Latest Inconel 625 Alloy Bar Price List per Kg

2026-06-17

The latest Inconel 625 alloy bar price per kg depends on nickel, molybdenum, niobium, and chromium raw material costs, as well as bar diameter, manufacturing route, heat treatment, surface finish, tolerance, inspection requirements, stock availability, order quantity, and delivery schedule. Inconel 625, also known as Alloy 625, UNS N06625, and W.Nr. 2.4856, is a nickel-chromium-molybdenum-niobium alloy widely used for offshore equipment, seawater systems, chemical processing, oil and gas components, pollution control equipment, aerospace parts, fasteners, pump shafts, valve stems, and high-temperature corrosion-resistant components. As a practical purchasing reference, standard industrial Inconel 625 round bar commonly costs approximately USD 30 to 60 per kg. Forged, cold drawn, precision ground, AMS-certified, tightly toleranced, or small-quantity bars may cost approximately USD 40 to 105 per kg or more. The final quotation should always be based on the exact diameter, length, quantity, specification, delivery condition, surface finish, testing scope, and shipping destination.

Latest Inconel 625 Alloy Bar Price List per Kg Overview

Inconel 625 alloy bar is one of the most widely purchased nickel alloy bar products because it provides a practical combination of corrosion resistance, strength, weldability, fabricability, and elevated-temperature performance. It is more expensive than Inconel 600 because it contains substantial molybdenum and niobium, but it is generally more readily available than highly specialized alloys such as Hastelloy C276 or Inconel 617.

The word “latest” is important in an Inconel 625 price page because nickel alloy prices are not fixed for long periods. Nickel is the largest raw material component, while molybdenum and niobium add significant alloy value. A supplier may therefore limit quotation validity to several days or several weeks, depending on market volatility and stock ownership.

Inconel 625 bar price is also affected by whether the supplier is quoting existing inventory or new mill production. Stock purchased at an earlier raw material price may be quoted differently from a new production batch calculated using current nickel and molybdenum costs.

Inconel 625 UNS N06625 Grade Identification

Inconel 625 is commonly identified as UNS N06625 and W.Nr. 2.4856. It may also be described as Alloy 625, Nickel Alloy 625, NiCr22Mo9Nb, or NC22DNb depending on the country, standard, or supplier.

Correct grade identification is necessary because Inconel 625 can be confused with Inconel 600, Inconel 718, Alloy 825, Hastelloy C276, or other nickel-chromium-molybdenum alloys. These materials have different chemical compositions, strengthening mechanisms, corrosion behavior, heat treatment requirements, availability, and prices.

Inconel 625 Alloy Bar Chemical Composition

Inconel 625 is a nickel-chromium-molybdenum-niobium alloy. Its high nickel content provides a stable corrosion-resistant matrix. Chromium improves oxidation resistance and resistance to many oxidizing media. Molybdenum improves resistance to pitting, crevice corrosion, and reducing acids. Niobium plus tantalum stiffens and strengthens the nickel-chromium matrix.

The alloy normally develops its useful strength through solid-solution strengthening. Standard Inconel 625 does not require the precipitation-hardening treatment used for Inconel 718 or X-750 to achieve its basic combination of strength and corrosion resistance.

Typical Limiting Chemical Composition

Element Specified Range or Limit Effect on Performance and Price
Nickel 58.0% minimum Main alloy base and major raw material cost component
Chromium 20.0–23.0% Supports oxidation resistance and broad corrosion resistance
Molybdenum 8.0–10.0% Improves localized corrosion resistance and solid-solution strength
Niobium plus Tantalum 3.15–4.15% Strengthens the matrix and increases alloy cost
Iron 5.0% maximum Controlled constituent of the alloy balance
Cobalt 1.0% maximum, if determined Controlled residual or minor element
Carbon 0.10% maximum Controlled for fabrication and metallurgical quality
Manganese 0.50% maximum Controlled minor element
Silicon 0.50% maximum Controlled residual and processing-related element
Aluminum 0.40% maximum Controlled minor element
Titanium 0.40% maximum Controlled minor element
Phosphorus 0.015% maximum Controlled impurity
Sulfur 0.015% maximum Kept low for hot workability and weld quality

Why the MTC Chemistry Should Be Checked

Buyers should check the actual heat analysis on the MTC rather than relying only on a supplier’s product name. Nickel, chromium, molybdenum, and niobium plus tantalum should meet the applicable specification. The heat number on the MTC should match the bar marking, label, packing list, and inspection report.

Nickel, Chromium, Molybdenum, and Niobium Cost Impact

The cost of Inconel 625 is strongly influenced by nickel, molybdenum, chromium, and niobium. Nickel has the largest percentage by weight, but molybdenum and niobium can have a disproportionate effect on the alloy surcharge because they are higher-value alloying elements and require careful melting control.

Nickel Cost Impact

Nickel represents at least 58% of the alloy. A movement in the LME nickel price therefore affects new mill-production costs, alloy surcharges, and supplier replacement value. However, finished Inconel 625 bar is not priced as raw nickel plus a small margin. It includes melting, remelting, forging, rolling, heat treatment, inspection, process loss, financing, and inventory cost.

Chromium Cost Impact

Chromium accounts for approximately 20% to 23% of Inconel 625. It provides oxidation resistance and supports the alloy’s performance in oxidizing chemical environments. Chromium generally has a lower cost impact than nickel or molybdenum, but its large percentage still contributes materially to the alloy surcharge.

Molybdenum Cost Impact

Molybdenum content is approximately 8% to 10%. It is essential for resistance to pitting, crevice corrosion, reducing acids, and chloride-containing media. Molybdenum price changes can significantly affect Alloy 625 production cost.

Niobium and Tantalum Cost Impact

Niobium plus tantalum content is approximately 3.15% to 4.15%. These elements support solid-solution strengthening and distinguish Alloy 625 from many simpler nickel-chromium alloys. Their cost, availability, and melting control contribute to the price premium over Inconel 600.

Alloying Element Approximate Content Relative Cost Influence Main Performance Contribution
Nickel 58% minimum Very high Base matrix, corrosion resistance, ductility, and thermal stability
Chromium 20–23% Medium to high Oxidation resistance and resistance to oxidizing media
Molybdenum 8–10% High Pitting, crevice corrosion, acid resistance, and strengthening
Niobium plus Tantalum 3.15–4.15% High Matrix strengthening and elevated-temperature performance

Inconel 625 Round Bar Price per Kg by Diameter Range

Inconel 625 round bar price varies with diameter because small rods and large forged bars require different manufacturing routes. Medium stock diameters normally offer the most competitive price per kg. Small diameters may require cold drawing or precision grinding, while very large diameters may require custom forging, rough turning, heat treatment, and UT.

Diameter-Based Price Reference

Diameter Range Reference Price per Kg Typical Supply Condition
3–10 mm USD 48–95/kg Cold drawn, polished, or precision ground rod
12–20 mm USD 40–82/kg Cold drawn, peeled, ground, or small hot-finished bar
22–80 mm USD 30–58/kg Common stock round bar and general machining blank
85–150 mm USD 35–68/kg Hot rolled, forged, or rough-turned bar
160–250 mm USD 40–82/kg Large forged bar, often requiring heat treatment and UT
Above 250 mm Custom quotation Project-specific forging, rough machining, and inspection

Why Medium Diameters Are Often More Economical

Medium diameters are frequently produced and stocked, allowing manufacturers and suppliers to spread production and inventory costs over larger quantities. Small rods require more finishing per kilogram, while large bars involve heavier forging equipment, longer heat-treatment cycles, slower cooling, and more inspection.

Small-Diameter vs Large-Diameter Alloy Bar Price Differences

A small-diameter bar is not automatically cheaper per kilogram. Although its total weight is lower, producing a small precision rod may involve multiple cold-drawing passes, intermediate annealing, straightening, surface finishing, and dimensional inspection.

Large-diameter bars have a different cost structure. They may require forging from a larger billet or ingot, repeated reheating, controlled forging reduction, solution treatment, rough turning, ultrasonic testing, and longer machining times.

Small-Diameter Bar Cost Factors

Small-Bar Requirement Cost Effect
Cold drawing Adds reduction passes, lubrication, intermediate annealing, and straightening
Precision grinding Adds grinding time, inspection, and surface protection
Tight straightness Requires controlled straightening and final inspection
Small order quantity Raises unit cost because setup and documentation costs are not diluted

Large-Diameter Bar Cost Factors

Large-Bar Requirement Cost Effect
Custom forging Requires large equipment, multiple reheats, and controlled reduction
Solution annealing Requires long furnace occupancy and controlled cooling
Rough turning Removes scale and provides a machinable surface
Ultrasonic testing Checks internal soundness for critical or heavy-section parts
Low production yield End discard, surface removal, and test samples increase effective cost

Hot Rolled, Forged, Cold Drawn, and Precision Ground Bar Prices

The processing route is one of the clearest reasons for price differences between Inconel 625 bar quotations. Hot-rolled bar normally has the lowest conversion cost, while precision ground bar normally has the highest finishing cost.

Hot Rolled Inconel 625 Bar

Hot-rolled bar is suitable for general machining blanks, shafts, supports, valve parts, and components that will undergo substantial material removal. Its initial price is usually lower, but the buyer should allow for surface scale, diameter tolerance, ovality, and machining allowance.

Forged Inconel 625 Bar

Forged bar is used for large diameters, heavy components, rings, flanges, pressure parts, and custom blanks. Its price depends on ingot size, forging reduction, heat treatment, rough machining, UT acceptance level, and required mechanical properties.

Cold Drawn Inconel 625 Bar

Cold drawn bar provides improved diameter tolerance, surface finish, and strength. It is commonly used for small rods, fastener stock, pins, shafts, and precision components. Intermediate annealing may be necessary because Alloy 625 work-hardens more rapidly than many stainless steels.

Precision Ground Inconel 625 Bar

Precision ground bar is used where the buyer requires a close diameter tolerance, controlled roundness, high straightness, and smooth surface roughness. It can reduce final machining time but normally carries the highest price per kg.

Bar Condition Reference Price Range Main Advantage Main Cost Addition
Hot Rolled USD 30–50/kg Economical general machining blank Limited finishing
Forged USD 38–78/kg Large size and heavy-section capability Forging, heat treatment, UT, and rough turning
Cold Drawn USD 42–82/kg Improved tolerance and strength Drawing passes, annealing, and straightening
Peeled or Turned USD 33–62/kg Cleaner surface and reduced machining allowance Surface removal and dimensional control
Precision Ground USD 50–105/kg Tight tolerance and smooth surface Grinding, inspection, and protective packing

Annealed and Solution-Annealed Condition Cost Differences

Inconel 625 may be supplied in soft-annealed and solution-annealed conditions. The correct condition depends largely on service temperature and required corrosion or creep performance. These conditions should not be treated as identical when comparing prices.

Soft-Annealed Inconel 625

Soft-annealed Alloy 625 is widely used for wet-corrosion applications below approximately 600°C. A common annealing range is approximately 950°C to 1050°C. This condition provides good ductility, fabricability, and resistance to pitting, crevice corrosion, chloride stress corrosion cracking, acids, alkalis, seawater, and brackish water.

Solution-Annealed Inconel 625

Solution-annealed Alloy 625 is generally used for high-temperature applications above approximately 600°C where improved creep strength and microstructural stability are required. A typical solution-treatment range is approximately 1080°C to 1160°C, followed by suitable cooling.

Inconel 625 Alloy Bar

Cost Difference Between the Conditions

The solution-annealed condition can cost more because it uses a higher furnace temperature, requires more careful furnace control, and may be combined with additional testing for high-temperature applications. The actual price difference is usually smaller than the difference caused by precision grinding or custom forging, but it should still be identified in the quotation.

Condition Typical Application Direction Heat-Treatment Range Price Consideration
Soft Annealed Wet corrosion, chemical processing, marine, offshore, and oil and gas Approximately 950–1050°C Common industrial condition with broad availability
Solution Annealed High-temperature applications and improved creep performance Approximately 1080–1160°C May carry a heat-treatment and testing premium

Do Not Select the Condition by Price Alone

A lower-priced soft-annealed bar may not be suitable for a continuously loaded component above 600°C. Similarly, paying for solution-annealed material may not provide a commercial advantage for a room-temperature seawater shaft if the required wet-corrosion condition is already satisfied by standard annealed bar.

Stock Size vs Custom Size Inconel 625 Bar Price

Stock size Inconel 625 bar is generally more economical than custom production. Alloy 625 is widely stocked compared with many other nickel alloys, but availability still varies by diameter, length, specification, condition, and country.

Advantages of Stock Material

Stock bars can reduce lead time, MOQ, production risk, and setup cost. Buyers may obtain a better total cost by selecting the next larger stock diameter and machining it to the required dimension.

Custom Production Requirements

Custom production may involve melting, forging, rolling, heat treatment, peeling, grinding, testing, and special marking. A mill may require an MOQ much larger than the buyer’s finished requirement because production yield includes end discard, surface removal, samples, and process losses.

Comparison Item Stock Size Bar Custom Size Bar
Price per kg Usually lower Usually higher
Minimum quantity May allow one bar or several cut pieces May require a full mill or forging batch
Lead time Shorter after document approval Longer because of production and testing
Dimension flexibility Limited to available stock Can be produced closer to the drawing size
Specification Limited to the original stock certification Can be planned for a particular specification

Existing Stock Cannot Always Be Recertified

A stock bar produced to ASTM B446 cannot automatically be converted into AMS 5666 material simply because the chemistry appears similar. The original melting route, processing history, heat treatment, testing, and certification must meet the required specification.

Tolerance, Surface Finish, Cutting, and Machining Cost Factors

A quotation for standard mill-finish bar is not comparable with a quotation for precision-ground bar. Tolerance, straightness, surface finish, cutting pattern, and machining scope can add substantial value to the material.

Diameter Tolerance

Standard hot-rolled or forged tolerance is normally the lowest-cost option. Tighter diameter tolerance may require peeling, turning, cold drawing, or centerless grinding. The tighter the tolerance, the greater the inspection frequency and rejection risk.

Straightness and Roundness

Long shafts and rods may require controlled straightness per meter. Precision ground bars may also need roundness and ovality limits. These requirements should be stated numerically rather than described only as “high precision.”

Surface Finish

Black, hot-rolled, pickled, peeled, polished, turned, and ground surfaces have different costs. A ground bar may reduce machining time, but the buyer should confirm whether the quoted surface roughness and defect-removal level meet the drawing.

Cutting Service

Cut-to-length service includes saw time, kerf loss, identification transfer, dimensional inspection, and repacking. Many short pieces usually cost more per kg than one full-length bar.

Machining Service

Suppliers may provide rough turning, drilling, milling, end facing, chamfering, threading, or finished-part machining. Inconel 625 work-hardens and generates significant cutting heat, so machining time and tool consumption are higher than for carbon steel.

Requirement Lower-Cost Option Higher-Cost Option
Diameter tolerance Standard mill tolerance Ground tolerance with inspection report
Surface Hot rolled or pickled Peeled, polished, or precision ground
Length Full random or standard length Multiple fixed lengths with tight tolerance
Ends Saw cut Faced, chamfered, deburred, or machined
Inspection Standard dimensional check Full dimensional report and third-party verification

Order Quantity, MOQ, Lead Time, and Raw Material Price Impact

Order quantity and availability can change Inconel 625 bar price as much as the alloy surcharge. Small orders may carry a high unit price because the supplier must still review certificates, cut the material, transfer markings, inspect the pieces, prepare export documents, and pack the order.

Order Quantity

Larger quantities normally reduce processing and handling cost per kilogram. However, the price may not fall proportionally if the order exceeds available stock and requires new production at a higher raw material price.

Minimum Order Quantity

A stockholder may sell one piece or part of a bar. A manufacturer may require a full billet, production batch, forging batch, or minimum tonnage. The MOQ should therefore be confirmed before comparing a manufacturer’s theoretical base price with a stock supplier’s cut-piece price.

Lead Time

Ready stock usually offers the shortest lead time. Custom forged bar may require billet scheduling, forging, heat treatment, rough machining, UT, mechanical testing, certificate preparation, and transport from the mill. Urgent delivery may require priority processing or air freight.

Raw Material Price

Nickel, molybdenum, niobium, and chromium markets influence new production and replacement cost. Suppliers may therefore state a quotation validity period. A long-validity fixed price may include a risk premium.

Commercial Factor More Economical Situation Higher-Cost Situation
Quantity Regular batch or full bars Prototype quantity or very small cut pieces
MOQ Suitable stock available New mill production required
Lead time Normal processing and sea freight Priority processing and air shipment
Raw material market Stable nickel and molybdenum prices Rapidly rising or volatile alloy markets
Price validity Short validity linked to current stock Long fixed-price validity requiring supplier risk coverage

Inconel 625 Bar Price Compared with Inconel 600, 718, and Hastelloy C276

Inconel 625 usually costs more than Inconel 600 because it contains molybdenum and niobium and provides much stronger resistance to pitting, crevice corrosion, seawater, chlorides, and many acids. Its price may overlap with Inconel 718 depending on heat treatment and certification. Hastelloy C276 is frequently more expensive because of its high molybdenum and tungsten content and more specialized supply.

Price and Performance Comparison

Alloy Typical Relative Price Main Cost Reason Main Performance Direction
Inconel 600 Lower Simpler Ni-Cr-Fe composition without major Mo or Nb addition General oxidation and corrosion resistance
Inconel 625 Medium to high High nickel, molybdenum, chromium, and niobium content Marine, chemical, chloride, offshore, and corrosion-resistant service
Inconel 718 Medium to high; aerospace conditions may be higher Complex precipitation-hardening chemistry and heat treatment Very high mechanical strength up to approximately 650°C
Hastelloy C276 Often higher than 625 High molybdenum, chromium, tungsten, and specialized corrosion-alloy production Severe chemical corrosion, wet chlorine, reducing acids, and mixed media

Inconel 625 vs Inconel 600 Price

Inconel 600 is normally cheaper and can be suitable where general oxidation resistance, caustic resistance, and nickel-chromium performance are sufficient. Inconel 625 justifies the higher cost when chloride pitting, seawater, aggressive chemical media, or greater strength is involved.

Inconel 625 vs Inconel 718 Price

Standard industrial Inconel 625 and Inconel 718 bar prices can overlap. Fully heat-treated aerospace Inconel 718 may cost more because of precipitation-hardening cycles, mechanical testing, and traceability. The choice should be based on strength and corrosion requirements, not only alloy price.

Inconel 625 vs Hastelloy C276 Price

Hastelloy C276 frequently carries a higher price because it contains approximately 15% to 17% molybdenum and 3% to 4.5% tungsten. It is selected for severe chemical environments where Alloy 625 may not provide enough resistance. For seawater, offshore, and broad corrosion-resistant engineering use, Inconel 625 may provide a more economical balance.

How to Obtain an Accurate Inconel 625 Alloy Bar Quotation

To obtain an accurate quotation, the buyer should provide enough technical and commercial information for the supplier to identify the correct stock or production route. An inquiry containing only “Inconel 625 bar price” can receive only a broad reference range.

Required RFQ Information

RFQ Item Example Why It Is Required
Grade Inconel 625 / UNS N06625 / W.Nr. 2.4856 Confirms the correct nickel alloy
Specification ASTM B446, ASME SB446, AMS 5666, or customer specification Defines processing, testing, and certification
Product form Round bar, forged bar, flat bar, or precision ground rod Determines the production route
Dimensions Diameter, length, and dimensional tolerance Determines weight, stock availability, and processing cost
Quantity Pieces, meters, kilograms, or full bars Affects MOQ and unit price
Condition Soft annealed, solution annealed, hot rolled, forged, peeled, or ground Affects corrosion, temperature performance, and price
Testing MTC, PMI, UT, hardness, tensile, or third-party inspection Defines quality-control cost and acceptance scope
Processing Cutting, facing, chamfering, rough turning, or grinding Determines value-added processing cost
Delivery terms EXW, FOB, CIF, DAP, or DDP destination Determines which logistics and tax costs are included

Clear Quotation Request Example

A clear inquiry can be written as: Inconel 625 round bar, UNS N06625, ASTM B446, diameter 50 mm, length 3000 mm, quantity 600 kg, soft-annealed and peeled condition, with EN 10204 3.1 MTC and heat-number traceability. Please quote full-length and cut-to-length options separately, including price per kg, cutting cost, stock status, lead time, packing, and FOB shipping terms.

Additional Information for High-Temperature Service

If the bar will operate above approximately 600°C, the RFQ should state the actual temperature, stress condition, exposure duration, and requirement for solution-annealed material. If creep, stress rupture, or elevated-temperature tensile testing is required, it must be stated before quotation.

Inconel 625 Alloy Bar

Additional Information for Marine and Chemical Service

For seawater, sour service, acid, or chloride applications, the buyer should state the medium, concentration, operating temperature, pressure, and applicable NACE or project requirements. This helps the supplier confirm whether standard Alloy 625 condition is suitable.

Latest Inconel 625 Alloy Bar Price List per Kg Related Questions

How much is Inconel 625 alloy bar per kg?

Standard industrial Inconel 625 round bar commonly costs approximately USD 30 to 60 per kg. Forged, cold drawn, precision ground, AMS-certified, specially tested, small-quantity, or custom-size bars may cost approximately USD 40 to 105 per kg or more. The final price depends on diameter, length, quantity, specification, heat treatment, tolerance, surface finish, testing, stock availability, and delivery terms.

Why is large-diameter Inconel 625 bar more expensive?

Large-diameter Inconel 625 bar may require custom forging, repeated reheating, controlled forging reduction, solution annealing, rough turning, ultrasonic testing, and longer processing time. Large bars also have higher production loss and may require special handling and packing. These factors can raise both the price per kg and the total order value.

Is Inconel 625 more expensive than Inconel 718 and Hastelloy C276?

Inconel 625 and Inconel 718 prices can overlap. Standard Alloy 625 may cost more or less depending on size and availability, while fully heat-treated aerospace Inconel 718 can be more expensive because of aging treatment and certification. Hastelloy C276 is often priced higher than Inconel 625 because of its greater molybdenum and tungsten content and more specialized corrosion-resistant supply. The correct alloy should be selected according to service conditions rather than price alone.
