Inconel 617 alloy round bar price per kilogram

2026-06-18

Inconel 617 alloy round bar price per kilogram is commonly about USD 45 to 90 per kg for standard industrial stock sizes. Large forged bars, small precision rods, tight-tolerance ground bars, special inspection orders, and custom production may cost approximately USD 65 to 145 per kg or more. Inconel 617, also known as Alloy 617 and UNS N06617, is a nickel-chromium-cobalt-molybdenum alloy developed for high-temperature strength, oxidation resistance, carburization resistance, creep performance, and long-term metallurgical stability. Its relatively high cobalt, nickel, chromium, and molybdenum contents make it more expensive than many conventional nickel alloy bars. The final Inconel 617 round bar price depends on diameter, length, quantity, specification, solution-annealed condition, surface finish, dimensional tolerance, cutting, machining, testing, stock availability, lead time, and delivery destination.

Inconel 617 Alloy Round Bar Price per Kilogram Overview

Inconel 617 round bar is a specialized high-temperature alloy product used for machining furnace parts, gas turbine components, combustion hardware, heat-treatment fixtures, petrochemical equipment, high-temperature fasteners, valve parts, shafts, supports, and power-generation components. It is not normally selected as a low-cost general corrosion-resistant bar. Its commercial value comes from its ability to retain useful strength and resist oxidation and carburization under prolonged high-temperature exposure.

The price per kilogram includes much more than the cost of nickel. Alloy production may involve controlled melting, billet preparation, forging or rolling, solution annealing, straightening, peeling, grinding, mechanical testing, ultrasonic inspection, certification, stock financing, cutting, packing, and international logistics.

Inconel 617 is also less commonly stocked than Inconel 600 or Inconel 625. A standard diameter available from existing inventory may therefore be priced much lower than a non-standard diameter requiring new mill production.

Typical Commercial Price Position

Inconel 617 Round Bar Type Reference Price per Kilogram Typical Purchasing Situation
Standard hot-rolled round bar USD 45–75/kg Common industrial machining blank with standard mill tolerance
Solution-annealed and peeled bar USD 50–90/kg Cleaner surface and confirmed high-temperature delivery condition
Forged round bar USD 55–105/kg Large diameters, heavy sections, and custom machining blanks
Cold-drawn small-diameter bar USD 65–115/kg Small rods requiring better tolerance and surface condition
Precision-ground round bar USD 75–145/kg Close-tolerance shafts, rods, pins, and precision components
Specially tested or project-certified bar Project quotation UT, elevated-temperature testing, third-party inspection, or special traceability

These prices are budgetary material references. They do not automatically include freight, insurance, import duties, taxes, anti-dumping duties, destination charges, or customer-specific third-party inspection.

Direct Answer: How Much Does Inconel 617 Round Bar Cost per Kg?

The direct answer is that Inconel 617 round bar commonly costs approximately USD 45 to 90 per kg for standard industrial orders. Medium-diameter stock bars in a solution-annealed or hot-finished condition are normally within this range.

Prices can increase to approximately USD 65 to 145 per kg when the order involves a large forged diameter, a very small cold-drawn rod, precision grinding, tight straightness, small purchase quantity, special heat treatment, ultrasonic testing, elevated-temperature mechanical testing, or urgent production.

Quick Inconel 617 Price Reference

Supply Description Budgetary Price Price Position
Stock bar, standard diameter USD 45–80/kg Usually the most economical supply option
Stock bar cut into fixed lengths USD 48–88/kg Includes saw cutting, kerf loss, marking, and repacking
Large custom-forged bar USD 60–115/kg Higher forging, heat-treatment, and inspection cost
Ground bar with tight diameter tolerance USD 75–145/kg Includes peeling, straightening, grinding, and dimensional inspection
Small sample or prototype quantity Supplier-specific premium Minimum processing and documentation charges raise the unit price

Why a Fixed Online Price May Be Misleading

An online price may apply only to one diameter, one surface condition, one origin, or one minimum quantity. It may exclude heat treatment, certificates, cutting, inspection, and freight. Some advertised prices also refer to old stock, offcuts, or material without the project-specific specification required by the buyer.

For a meaningful comparison, buyers should confirm whether each quotation covers the same UNS grade, standard, diameter, length, condition, surface finish, testing scope, certificate type, packing, and delivery term.

Inconel 617 UNS N06617 Grade Identification

Inconel 617 is generally identified as UNS N06617. Its common European material number is W.Nr. 2.4663, while some older technical literature may show 2.4663a. It may also be described as Alloy 617, NiCr23Co12Mo, NiCr22Co12Mo9, or Nicrofer 5520 Co.

The UNS number should appear on the purchase order, quotation, material test certificate, bar marking, packing label, and inspection report. A generic description such as “Inconel round bar” is not sufficient because Inconel 600, 601, 617, 625, 718, and X-750 have different compositions and properties.

Common Grade Designations

Designation Meaning Purchasing Note
Inconel 617 Common trademark-style material name Frequently used in commercial RFQs and product descriptions
Alloy 617 Generic alloy description Commonly used by manufacturers and stockholders
UNS N06617 Unified Numbering System designation Most important international grade identifier
W.Nr. 2.4663 European material number Frequently shown on European drawings and certificates
NiCr23Co12Mo Composition-based European designation Highlights chromium, cobalt, and molybdenum content
Nicrofer 5520 Co Alternative commercial designation May appear in mill data sheets and older specifications

Common Round Bar Specifications

DIN 17752 Nickel and nickel alloy rod and bar May appear on German or European purchase documents
VdTÜV 485 High-temperature pressure-material approval reference Relevant to selected European pressure applications

Inconel 617 Round Bar Chemical Composition

Inconel 617 is a nickel-chromium-cobalt-molybdenum alloy with aluminum and controlled carbon additions. Nickel provides the stable austenitic base. Chromium and aluminum provide high-temperature oxidation resistance. Cobalt and molybdenum provide solid-solution strengthening. Controlled carbon contributes carbide strengthening and supports creep performance.

Typical Limiting Chemical Composition

Element Specified Range or Limit Main Function
Nickel 44.5% minimum Provides the nickel-base matrix, ductility, corrosion resistance, and thermal stability
Chromium 20.0–24.0% Improves oxidation resistance and high-temperature corrosion resistance
Cobalt 10.0–15.0% Supports solid-solution strength and long-term high-temperature stability
Molybdenum 8.0–10.0% Provides solid-solution strengthening and supports creep performance
Aluminum 0.8–1.5% Works with chromium to improve protective oxide-scale formation
Carbon 0.05–0.15% Supports carbide formation and high-temperature creep strength
Iron 3.0% maximum Controlled constituent of the alloy balance
Manganese 1.0% maximum Controlled minor element
Silicon 1.0% maximum Controlled residual and processing-related element
Titanium 0.6% maximum Controlled minor element
Copper 0.5% maximum Controlled residual element
Sulfur 0.015% maximum Kept low to support hot workability and material quality
Boron 0.006% maximum Controlled trace element affecting grain-boundary behavior

Why the Actual Heat Analysis Matters

The supplier should provide an MTC showing the actual chemical analysis of the supplied heat. The values should comply with the requested ASTM, ASME, AMS, or project specification. Heat-number identity should be maintained after a full bar is cut into smaller pieces.

Nickel, Chromium, Cobalt, and Molybdenum Cost Impact

Nickel, chromium, cobalt, and molybdenum account for most of the raw material value of Inconel 617. Cobalt is one of the most important reasons the alloy normally costs more than Inconel 600 and often more than Inconel 625.

Nickel Cost Impact

Nickel forms the principal alloy base. Changes in global nickel prices affect new mill production, alloy surcharges, supplier replacement costs, and quotation validity. However, finished round bar costs substantially more than raw nickel because of alloying, melting, conversion, heat treatment, testing, and inventory costs.

Chromium Cost Impact

Chromium represents approximately 20% to 24% of the alloy. It supports oxidation resistance and resistance to hot corrosive atmospheres. Although chromium is normally less expensive than cobalt or molybdenum, its high percentage gives it a meaningful influence on total alloy cost.

Cobalt Cost Impact

Inconel 617 contains approximately 10% to 15% cobalt. Cobalt is a relatively high-cost and price-sensitive raw material. This significant cobalt addition differentiates Alloy 617 from Inconel 600 and Inconel 625 and is a major reason for its higher selling price.

Molybdenum Cost Impact

Molybdenum content is approximately 8% to 10%. Molybdenum contributes solid-solution strengthening and high-temperature creep performance. Its market price and conversion cost can materially affect Alloy 617 mill surcharges.

Element Typical Content Relative Price Influence Main Performance Contribution
Nickel 44.5% minimum Very high Base matrix, thermal stability, ductility, and corrosion resistance
Chromium 20–24% Medium to high Oxidation and high-temperature corrosion resistance
Cobalt 10–15% Very high Solid-solution strength and high-temperature stability
Molybdenum 8–10% High Solid-solution strengthening and creep performance

Inconel 617 Round Bar Price by Diameter Range

Diameter has a strong influence on Inconel 617 round bar price. Medium stock diameters usually offer the most economical price per kilogram. Small rods may require cold drawing or precision grinding. Large bars often require custom forging, solution treatment, rough turning, ultrasonic inspection, and special handling.

Price per Kilogram by Diameter

Diameter Range Reference Price per Kilogram Typical Supply Route
3–10 mm USD 80–145/kg Cold drawn, straightened, polished, or precision ground
12–20 mm USD 65–120/kg Cold drawn, peeled, ground, or small hot-finished bar
22–80 mm USD 45–88/kg Common hot-rolled, forged, or peeled stock bar
85–150 mm USD 52–100/kg Hot-rolled or forged bar with solution treatment
160–250 mm USD 60–120/kg Custom-forged, rough-turned, and frequently UT-tested bar
Above 250 mm Custom quotation Project-specific forging, heat treatment, machining, and inspection

Round Bar Weight and Total Order Value

Even when two diameters have a similar price per kilogram, the larger bar has a much higher total order value. Round bar weight increases with the square of its diameter. Buyers should therefore evaluate both the quoted price per kg and the calculated total weight.

Diameter Approximate Weight per Meter Commercial Effect
20 mm About 2.6 kg/m Low total weight, but small-size processing may increase unit price
50 mm About 16.4 kg/m Common machining size with relatively stable price
100 mm About 65.7 kg/m High total order value and heavier cutting requirements
200 mm About 263 kg/m Usually forged and may require special lifting, UT, and packing

The weights above are approximate and based on a nominal density of about 8.36 to 8.4 g/cm³. Actual invoiced weight should be calculated from the supplied dimensions or verified by weighing.

Small-Diameter vs Large-Diameter Round Bar Price Differences

A smaller bar does not necessarily have a lower price per kilogram. A small precision rod may cost more per kg than a 50 mm stock bar because more processing is required for every kilogram of finished material.

Why Small-Diameter Bars Can Cost More

Small Inconel 617 rods may require multiple drawing passes, intermediate annealing, descaling, straightening, polishing, grinding, and frequent dimensional inspection. Production yield can also be lower when strict surface and straightness requirements are applied.

Small-Bar Cost Factor Effect on Price
Cold-drawing passes Add equipment time, tooling, lubrication, and process control
Intermediate annealing Add furnace time and handling between reductions
Straightness control Requires additional straightening and inspection
Precision grinding Adds finishing time and reduces material yield
Small order quantity Spreads setup, testing, and documentation costs over fewer kilograms

Why Large-Diameter Bars Can Cost More

Large Inconel 617 bars normally require a forging route. Large ingots or billets must be reheated and forged with enough reduction to refine the structure. Subsequent solution annealing, slow handling, rough turning, UT, and mechanical testing add further cost.

Large-Bar Cost Factor Effect on Price
Large billet or ingot requirement Raises raw material commitment and production MOQ
Multiple forging heats Add furnace energy, press time, and labor
Long solution-treatment cycle Requires substantial furnace capacity and controlled cooling
Rough turning Removes scale and surface defects but reduces finished yield
Ultrasonic testing Adds inspection cost and possible rejection risk

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

The processing condition is one of the clearest price differences between Inconel 617 quotations. A black hot-rolled bar is generally the least expensive. A precision-ground bar with tight straightness and diameter tolerance is generally the most expensive.

Hot-Rolled Inconel 617 Round Bar

Hot-rolled bar is suitable for general machining blanks where significant surface material will be removed. It normally has standard mill tolerance, surface scale, and greater diameter variation than peeled or ground material.

The lower purchase price should be compared with the machining allowance required to remove surface scale and reach the finished dimension.

Forged Inconel 617 Round Bar

Forged bar is used for large diameters and heavily loaded high-temperature components. Its price depends on billet size, forging ratio, number of reheats, heat treatment, rough machining, UT acceptance, mechanical tests, and final dimensions.

Cold-Drawn Inconel 617 Bar

Cold-drawn bar offers better dimensional control and surface quality for small diameters. Cold working can increase strength and hardness, but the final properties must still conform to the required specification and delivery condition.

Inconel 617 alloy round bar

Precision-Ground Inconel 617 Bar

Precision grinding provides tight diameter tolerance, controlled roundness, improved straightness, and smooth surface finish. It is used for shafts, pins, valve components, rods, fastener blanks, and other close-tolerance parts.

Bar Condition Reference Price Main Advantage Main Cost Addition
Hot rolled USD 45–75/kg Economical general machining blank Limited finishing and standard tolerance
Forged USD 55–105/kg Large diameters and heavy-section capability Forging, reheating, heat treatment, and UT
Cold drawn USD 65–115/kg Improved diameter tolerance and surface Drawing passes, annealing, and straightening
Peeled or rough turned USD 50–90/kg Cleaner surface and reduced machining allowance Surface removal and dimensional control
Precision ground USD 75–145/kg Tight tolerance and smooth surface finish Grinding, inspection, straightening, and protective packing

Solution-Annealed and Other Heat Treatment Cost Differences

Inconel 617 is a solid-solution-strengthened and carbide-strengthened alloy. It is not a conventional age-hardenable alloy like Inconel 718 or Inconel X-750. Round bar is generally supplied in a solution-annealed condition when optimum high-temperature properties are required.

Solution-Annealed Condition

Solution annealing dissolves unwanted phases, establishes the required austenitic structure, and prepares the material for high-temperature service. The exact temperature and cooling method should follow the applicable mill procedure, material specification, and product size.

Large bars require longer furnace cycles than small bars because the complete section must reach the required temperature. Controlled furnace loading and cooling are important to limit distortion and obtain consistent properties.

Stabilizing Heat Treatment

Some fabricated or welded Alloy 617 components may require a stabilizing heat treatment before service within certain intermediate-temperature ranges. This requirement is related to the final component and welding procedure rather than every standard round bar order, but it can add substantial furnace and inspection cost when specified.

Stress Relief and Customer-Specific Treatment

Customer drawings may request stress relief, post-weld heat treatment, or a specific thermal cycle. A non-standard cycle should be reviewed carefully because it may change carbide distribution, grain-boundary behavior, mechanical properties, and dimensional stability.

Heat Treatment Requirement Purpose Typical Price Effect
Standard solution annealing Provides the normal high-temperature delivery condition Normally included in compliant mill production
Re-solution treatment after processing Restores the required structure after significant cold work or fabrication Adds furnace, handling, and testing cost
Stabilizing treatment Reduces specific cracking risks in selected welded applications Medium to high, depending on component size and furnace time
Customer-specific thermal cycle Meets project or engineering requirements Project-specific and may require qualification testing

Heat Treatment Must Be Documented

The MTC should identify the delivery condition or applicable heat-treatment requirement. If a buyer needs furnace charts, time-temperature records, hardness results, or post-treatment mechanical testing, these items should be stated before quotation.

Stock Size vs Custom Size Inconel 617 Round Bar Price

Stock size is normally the most economical purchasing option. Inconel 617 is a specialized alloy, so stock availability may be limited to selected diameters and lengths. Choosing a slightly larger available diameter can be more economical than producing an exact custom size.

Stock Size Advantages

Stock material can reduce MOQ, production lead time, mill setup cost, and raw material price exposure. A stockholder may also sell one full bar or several cut pieces, while a mill may require a complete production batch.

Custom Size Requirements

Custom production may require a new melting or billet allocation, forging, rolling, heat treatment, rough turning, testing, and certification. The quantity required for production may be substantially larger than the buyer’s finished net weight because of end discard, scale removal, machining allowance, samples, and process losses.

Comparison Item Stock Size Bar Custom Size Bar
Price per kg Normally lower Normally higher
MOQ May allow one bar or cut pieces May require a full forging or mill batch
Lead time Short after document approval Longer because of production and inspection
Dimension flexibility Limited to inventory Can be produced closer to the drawing size
Specification Limited to the original stock certificate Can be planned for a specific standard or project
Risk Possible extra machining allowance Higher commitment, longer schedule, and production risk

Existing Stock Cannot Always Be Recertified

A stock bar manufactured to ASTM B166 cannot automatically be certified to AMS 5887 after production. The original melting method, manufacturing route, heat treatment, test samples, acceptance results, and documentation must satisfy the requested specification.

Surface Finish, Tolerance, Cutting, and Machining Cost Factors

Surface finish and dimensional requirements can change the final cost significantly. Buyers should not compare a black hot-rolled bar with a peeled or ground bar as if they were the same product.

Surface Finish

Common surface conditions include hot-rolled black surface, descaled, pickled, peeled, rough turned, polished, and centerless ground. Each additional operation removes material and adds processing time.

Diameter Tolerance

Standard mill tolerance is the least expensive. Tight diameter tolerance may require turning, peeling, cold drawing, or grinding. The price normally rises as tolerance becomes tighter because processing time and rejection risk increase.

Straightness and Roundness

Long shafts may require a maximum straightness deviation per meter. Precision bars may also require roundness, ovality, and surface-roughness limits. These requirements should be stated numerically in the RFQ.

Cutting Service

Saw cutting includes machine time, blade wear, kerf loss, end identification, length inspection, and repacking. Many short pieces normally have a higher unit cost than one full-length bar.

Machining Cost

Inconel 617 has high strength, low thermal conductivity relative to many steels, and a tendency to work harden. Machining therefore requires rigid equipment, appropriate carbide tooling, stable feed, controlled cutting speed, and effective cooling.

Requirement Lower-Cost Option Higher-Cost Option
Surface Hot rolled or descaled Peeled, polished, or precision ground
Diameter tolerance Standard mill tolerance h9, h8, h7, or customer-specific ground tolerance
Straightness Standard commercial straightness Precision straightness with inspection report
Length Random or full mill length Multiple fixed lengths with tight tolerance
Ends Standard saw cut Faced, chamfered, deburred, or machined ends
Machining Raw bar supply Rough turning, drilling, threading, or finished-part machining

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

Order quantity and MOQ influence both the price per kilogram and the practical ability to purchase Inconel 617. A stock supplier may sell a short cut piece, but a producing mill may require a complete billet, forging batch, or minimum production quantity.

Order Quantity

Larger regular orders generally have lower handling, cutting, inspection, and documentation costs per kilogram. However, if the required quantity exceeds available stock, part of the order may need new production at a different raw material cost.

Minimum Order Quantity

MOQ depends on the product condition. A stock hot-rolled bar may be sold by the piece. A custom-forged 280 mm bar may require several hundred kilograms or more because of billet size, forging loss, testing, and end discard.

Lead Time

Ready stock offers the shortest lead time. New production requires material scheduling, forging or rolling, solution annealing, rough machining, inspection, certification, and transport. Urgent delivery may require priority processing or air freight.

Raw Material Price and Quotation Validity

Nickel, cobalt, molybdenum, and chromium prices affect the replacement value of Alloy 617. Suppliers may therefore limit quotation validity. A longer fixed-price period may include a risk premium, especially when cobalt or nickel prices are volatile.

Commercial Factor More Economical Situation Higher-Cost Situation
Quantity Full bars or regular batch orders Samples, prototypes, or very small cut pieces
MOQ Suitable inventory already exists Custom mill or forging production is required
Lead time Standard schedule and sea freight Priority processing and air shipment
Raw material market Stable nickel, cobalt, and molybdenum prices Rapidly rising or volatile alloying-element prices
Price validity Short validity based on existing stock Long fixed validity requiring supplier risk coverage

Inconel 617 Round Bar Price Compared with Inconel 625 and Inconel 600

Inconel 617 round bar is normally more expensive than Inconel 600 and frequently more expensive than Inconel 625. The main reason is its substantial cobalt and molybdenum content, specialized high-temperature use, and lower stock availability.

Price and Performance Comparison

Alloy Budgetary Round Bar Price Main Cost Reason Main Performance Direction
Inconel 600 About USD 25–50/kg Simpler Ni-Cr-Fe composition without major Co or Mo additions General oxidation, heat, caustic, and corrosion resistance
Inconel 625 About USD 30–65/kg High nickel, chromium, molybdenum, and niobium contents Marine, chloride, offshore, chemical, and corrosion-resistant service
Inconel 617 About USD 45–90/kg High nickel, chromium, cobalt, and molybdenum plus specialized supply Very high-temperature creep, oxidation, carburization, and thermal stability

Inconel 617 vs Inconel 600 Price

Inconel 600 normally costs less because it does not contain major cobalt or molybdenum additions. It is suitable for many general heat-resistant and corrosion-resistant applications. However, it does not provide the same very high-temperature creep strength and long-term stability as Alloy 617.

Inconel 617 vs Inconel 625 Price

Inconel 625 is often less expensive and more readily available. It is normally the stronger choice for seawater, chlorides, offshore, wet chemical processing, and pitting or crevice-corrosion resistance.

Inconel 617 justifies its higher cost when the dominant requirements are very high-temperature strength, creep resistance, oxidation resistance, carburization resistance, and prolonged thermal exposure.

Select by Failure Mechanism, Not Price Alone

Using Alloy 617 for a seawater shaft may add cost without providing the main performance benefit. Using Inconel 625 or 600 for a highly stressed component exposed near 1000°C may save initial material cost but increase the risk of creep deformation, oxidation damage, or early replacement.

How to Obtain an Accurate Inconel 617 Round Bar Quotation

An accurate quotation requires complete technical and commercial information. An inquiry stating only “Inconel 617 round bar price per kg” can receive only a broad budgetary range.

Required RFQ Information

RFQ Item Example Why It Matters
Grade Inconel 617 / UNS N06617 / W.Nr. 2.4663 Confirms the correct alloy

Quantity Pieces, meters, kilograms, or full bars Affects MOQ and price per kilogram
Delivery condition Hot rolled, forged, solution annealed, peeled, or ground Affects properties, machining allowance, and cost
Tolerance Mill tolerance, h11, h9, or drawing tolerance Determines finishing and inspection requirements
Testing MTC, PMI, UT, tensile, hardness, or elevated-temperature test Affects quality-control scope and price
Delivery term EXW, FOB, CIF, DAP, or DDP Clarifies which logistics and import costs are included

Clear RFQ Example

A clear inquiry can be written as: Inconel 617 round bar, UNS N06617, ASTM B166, diameter 60 mm, length 3000 mm, quantity 600 kg, solution-annealed and peeled condition, with EN 10204 3.1 MTC and heat-number traceability. Please quote stock and new-production options separately, including price per kilogram, available quantity, cutting charge, lead time, packing, and FOB terms.

Additional Information for High-Temperature Applications

For high-temperature service, the buyer should provide operating temperature, applied stress, exposure duration, atmosphere, thermal cycling, and whether creep or stress-rupture data are required. A component operating continuously at 1000°C should not be specified in the same way as a part exposed intermittently to 700°C.

Additional Inspection Requirements

Large or critical bars may require ultrasonic testing, macrostructure testing, grain-size examination, room-temperature tensile testing, elevated-temperature tensile testing, creep testing, or third-party inspection. These requirements must be included before the supplier reserves stock or begins production.

Inconel 617 alloy round bar

Inconel 617 Alloy Round Bar Price per Kilogram Related Questions

How much is Inconel 617 round bar per kilogram?

Standard industrial Inconel 617 round bar commonly costs approximately USD 45 to 90 per kg. Large forged bars, small cold-drawn rods, precision-ground bars, tight-tolerance products, specially tested material, and small custom orders may cost approximately USD 65 to 145 per kg or more. The final price depends on diameter, length, quantity, specification, heat treatment, surface finish, tolerance, testing, stock availability, and delivery terms.

Why is Inconel 617 round bar more expensive than Inconel 625?

Inconel 617 contains approximately 10% to 15% cobalt in addition to high nickel, chromium, and molybdenum. Cobalt is an expensive alloying element, and Alloy 617 is produced and stocked in lower volumes than Inconel 625. Its specialized high-temperature forging, solution treatment, inspection, and certification requirements can further increase the price. Inconel 625 is generally more widely available and is focused more on marine and chemical corrosion resistance.

What information is needed to obtain an accurate Inconel 617 bar price?

The buyer should provide Inconel 617 / UNS N06617 grade identification, applicable ASTM, ASME, AMS, or customer specification, diameter, length, quantity, delivery condition, heat-treatment requirement, surface finish, tolerance, cutting requirement, inspection scope, certificate type, destination, and Incoterm. Without these details, a supplier can provide only a broad reference price per kilogram.
