In 2026, Inconel 718 price per kg ranges from about 25forlarge−volumeChineseroundbarto25forlarge−volumeChineseroundbarto250 or more for aerospace additive-manufacturing powder. Most buyers who request general quotes see bands of 30−30−65 per kilogram for common mill-product forms, according to market data from OEPipe and Voyage Metal. The exact figure depends on product form, order quantity, heat-treatment condition, certification level, and the current nickel market.
Why does one RFQ return 28/kgwhileanotherreturns28/kgwhileanotherreturns55/kg for the same alloy? The difference is rarely the base metal. It is what the buyer forgot to specify. A procurement manager in Southeast Asia once asked three suppliers for a budget price on Inconel 718 round bar. He omitted diameter, AMS condition, and certificate requirements. The quotes varied by 47% because one supplier priced black hot-rolled bar while another priced precision-ground AMS 5663 with EN 10204 3.1 certification. After he specified 50 mm diameter, AMS 5662, h9 tolerance, and a standard MTR, the three quotes landed within 4% of each other.
In this guide, we break down realistic 2026 price bands by form and quantity, explain what drives the cost, and show how to structure an RFQ that eliminates quote variance. You will also see how certification, condition, and regional sourcing change the final Inconel 718 price per kg.
Key Takeaways
- Inconel 718 price per kg in 2026 spans roughly 30−30−65 for standard mill products, with China factory-direct bar starting near $25/kg at 500+ kg quantities.
- Round bar, plate, pipe, forgings, and additive-manufacturing powder each carry different price bands; AM powder can exceed 120/kgandoftenreaches120/kgandoftenreaches160-$250/kg.
- Raw materials, vacuum melting, heat treatment, certification, and quantity drive most of the cost difference between two apparently similar quotes.
- AMS 5662/5663, NACE MR0175, EN 10204 3.2, and third-party inspection each add cost that should be itemized in the quotation.
- A detailed RFQ with grade, form, size, condition, finish, quantity, certification, and delivery terms can cut quote variance from 40-50% to under 10%.
How Much Does Inconel 718 Cost Per Kg in 2026?
The fastest way to understand Inconel 718 price per kg is to look at standard product forms and realistic China factory-direct bands. The table below is not a binding offer. It is a starting point for budgeting and RFQ discussions.
| Product Form | China Factory-Direct Range (USD/kg) | Typical MOQ | Notes |
|---|---|---|---|
| Round bar/rod | 25−25−45 | 100 – 500 kg | Lower end for black HR, higher for ground/precision |
| Plate/sheet | 44−44−110 | 200 – 1,000 kg | Thin plate and tight tolerances push price up |
| Pipe/tube (seamless) | 30−30−65 | 100 – 500 kg | Welded tube can be lower; cold-finished higher |
| Forgings/flanges / fittings | 40−40−65 | 500+ kg | Forging yield and machining allowance add cost |
| Additive manufacturing powder | 120−120−250+ | 10 – 50 kg | Particle size, sphericity, and oxygen content matter |
Quantity has a direct impact on the Inconel 718 price per kg. Mill-direct pricing improves once an order crosses 500 kg and again above 2,000 kg. Small test lots, cut lengths, or non-standard sizes sit at the top of each range.
| Quantity Tier | Price Impact vs. Base Range |
|---|---|
| Less than 100 kg | +30% to +60% above base |
| 100 – 500 kg | Base range |
| 500 – 2,000 kg | -10% to -20% below base |
| Above 2,000 kg | -15% to -30% below base; negotiable |
Regional pricing differs as well. In India, distributor listings for Inconel 718 round bar run about INR 3,000-5,000 per kg, or 36−36−60/kg at current exchange rates. North American and European mill prices for comparable certified bar often start 10−10−20/kg higher than China factory-direct, with longer lead times. Chinese supply makes sense when the manufacturer provides full MTRs, third-party inspection options, and export documentation.

What Makes Inconel 718 Expensive?
Inconel 718 is a precipitation-hardening nickel-chromium superalloy. Its nominal composition includes 50-55% nickel, 17-21% chromium, 4.75-5.50% niobium plus tantalum, 2.80-3.30% molybdenum, and smaller additions of titanium and aluminum. Each of these elements is more costly than the iron base of standard stainless steels.
Nickel is the single largest cost driver. The alloy contains roughly half nickel by weight, so movements in the LME nickel price flow directly into base material cost. In 2026, nickel has traded in a range around 17,000−17,000−20,000 per metric ton. A $2,000/ton move in nickel can shift the Inconel 718 cost per kg by several dollars. Suppliers often quote a base price plus an alloy surcharge that tracks prior-month nickel and niobium adjustments, similar to the mechanism Special Metals publishes for its alloy surcharge.
Niobium is another expensive component. Unlike titanium or aluminum, niobium is classified as a critical raw material with limited primary supply. Price spikes in niobium translate quickly into higher melt costs for Inconel 718.
Production complexity adds cost beyond raw materials. The alloy is usually melted by vacuum induction melting (VIM), then refined by electroslag remelting (ESR) or vacuum arc remelting (VAR) for aerospace-grade cleanliness. Each remelt step consumes energy, labor, and furnace time. After melting, the material is forged or rolled, heat treated, tested, and inspected. For demanding applications, ultrasonic non-destructive testing (NDT) and 100% spectral verification are standard.
Machinability also affects the delivered cost of finished components. Inconel 718 work-hardens rapidly and generates high cutting forces. Machine shops factor in slower speeds, shorter tool life, and higher scrap rates when pricing machined parts. A buyer who orders rough-machined forgings rather than raw bar will see those costs in the per-kg price.
Inconel 718 Price by Product Form
Round Bar and Rod
Round bar is the most commonly quoted form. The Inconel 718 round bar price from Chinese suppliers ranges from 25/kgforblackhot−rolledbarin500+kgquantitiesto25/kgforblackhot−rolledbarin500+kgquantitiesto45/kg for precision-ground, tight-tolerance bar in smaller lots. AMS 5663 aged bar usually carries a small premium over AMS 5662 solution-treated bar because of the extra aging cycle and mechanical testing. Round bar is a core product in our nickel alloy bar program. For detailed mechanical data, see our Inconel 718 properties reference.
Plate and Sheet
Plate and sheet command higher per-kg prices than bar because of lower rolling yields, tighter thickness tolerances, and more demanding inspection. China factory-direct plate ranges from about 44/kgto44/kgto110/kg. Thin sheet below 3 mm and aerospace-grade flatness requirements sit at the upper end of the band.
Pipe and Tube
Seamless pipe and tube prices fall between 30/kgand30/kgand65/kg. Welded tube can price below this band, while cold-drawn seamless tube with tight dimensional control prices above it. Heat treatment, hydrostatic testing, and NDT add cost for sour-service or pressure-vessel applications.
Forgings, Flanges, and Fittings
Forged products range from 40/kgto40/kgto65/kg. The price reflects forging yield, die wear, and the machining allowance required to reach final dimensions. Large flanges and complex fittings may be priced per piece rather than per kilogram because of the processing time involved.
Additive Manufacturing Powder
Inconel 718 powder price per kg is in a separate category. Plasma-atomized or gas-atomized powder for laser powder bed fusion (LPBF) sells for 120−120−250+/kg, with $160/kg as a common midpoint, according to data from Richconn and MWalloys. Cost depends on particle size distribution, sphericity, oxygen content, and lot certification. Powder is rarely a substitute for wrought bar or plate; it is used for complex aerospace, medical, or repair components where near-net-shape production offsets the material premium.
How Certification and Condition Change the Price
Two quotes for Inconel 718 price per kg can differ by 30% or more based on certification and condition. Buyers who specify only the alloy name invite suppliers to assume the cheapest acceptable interpretation.
Industrial-grade bar certified to ASTM B637 is the baseline. Moving to AMS 5662 adds aerospace-level heat treatment, tensile testing, and documentation. AMS 5663 adds the standard double-aging cycle and higher strength verification. The premium is usually 1−1−4/kg, but the cost can be larger if the supplier must perform the aging as a separate batch process.
NACE MR0175 / ISO 15156 sour-service compliance adds a hardness-control requirement, capping aged bar at 40 HRC. This may require a modified aging practice or 100% hardness verification, adding 2−2−5/kg for tested lots.
EN 10204 3.1 certification is the standard mill certificate. EN 10204 3.2 requires independent third-party inspection of the material at the mill, which adds inspector fees and scheduling cost. Third-party inspection by SGS, TUV, or BV can add 0.50−0.50−2.00/kg depending on lot size and test scope.
Last year, a North American aerospace distributor ordered AMS 5663 bar for fastener blanks. The machine shop complained the material was too hard and wore tooling prematurely. The correct choice was AMS 5662 bar, machined into finished parts, then aged to AMS 5663 properties. The distributor now specifies “solution-treated for machining” on every RFQ. You can read about the exact heat treatment cycles in our Inconel 718 heat treatment guide.
Inconel 718 Price Per Kg in China vs Other Regions
China Factory-Direct Pricing
China remains the largest producer and exporter of specialty alloy semi-finished products. Inconel 718 price in China for certified round bar often starts at 5−5−15/kg below Indian distributor pricing and at 10−10−20/kg below Western mill pricing for equivalent specifications. The advantage comes from integrated melting, forging, and rolling capacity, plus lower labor and energy costs.
The risk is not the country of origin. It is the supplier’s quality system. A reliable Chinese manufacturer provides full traceability, in-house spectrometer verification, EN 10204 3.1/3.2 certification, and third-party inspection support. Zhonggongte supplies Inconel 718 from Wuxi with MTRs, spectral reports, and optional NDT for every order.
India
Inconel 718 price per kg India is quoted by distributors rather than mills. Listings for round bar commonly fall between INR 3,000 and INR 5,000 per kg, or roughly 36−36−60/kg. Indian prices can be competitive for domestic projects, but export buyers should confirm whether the material is imported or locally produced and whether certificates meet their project standards.
North America and Europe
U.S. and European mills price Inconel 718 at a premium because of labor, energy, and regulatory costs. Lead times are also longer for non-stock items. Buyers choose Western mills when the project specification names a specific mill source, when defense or nuclear traceability requirements apply, or when logistics favor local supply. For general aerospace, oil and gas, or industrial applications, a certified Chinese supplier can deliver equivalent documentation at a lower landed cost.
2026 Price Forecast and Market Outlook
The Inconel 718 price forecast 2026 depends on nickel, demand, and supply-chain capacity. Nickel prices are expected to remain in the 17,000−17,000−20,000/metric-ton range barring a major supply disruption. Niobium supply is tighter and more volatile, which creates upside risk for Inconel 718 melt costs.
Demand drivers remain strong. Aerospace engine backlogs continue to absorb large volumes of wrought bar, forgings, and powder. Defense spending, energy-sector sour-service components, and additive-manufacturing growth add further demand. IMARC Group and other industry analysts project the global Inconel market to grow at a compound annual rate of roughly 5.5%, with alloy bar demand growing slightly faster.
Our base case is a 5-7% annual increase in finished-product prices, assuming nickel stays within the forecast range. If nickel breaks above $22,000/ton, price spikes of 10-15% are possible within a quarter. Buyers with large annual requirements can reduce this risk by negotiating quarterly pricing with alloy-surge caps or by placing blanket orders with scheduled releases.

Ask for an itemized breakdown. A clear quote separates base material, alloy surcharge, heat treatment, testing, certification, and freight. This makes it easy to compare suppliers and identify where one quote is saving or adding cost.
A Middle Eastern oilfield services firm needed 2,000 kg of NACE-compliant Inconel 718 round bar for wellhead components. Zhonggongte supplied VIM/ESR material with hardness capped at 40 HRC, third-party inspection, and seaworthy export packaging. The shipment cleared customer inspection on arrival and kept the project on schedule. Specific requirements produce specific results.
Frequently Asked Questions
Why is Inconel 718 so expensive?
The alloy contains about 50-55% nickel plus niobium, chromium, and molybdenum. It is melted and remelted under vacuum, heat-treated, and tested to aerospace or sour-service standards. Each step adds cost compared with standard stainless steel or low-alloy steel.
Is Inconel 718 cheaper than Inconel 625?
Not always. Inconel 718 is often priced slightly higher per kilogram than Inconel 625 for equivalent product forms because of its higher niobium content and more complex heat treatment. However, the difference can reverse depending on size, condition, and the current nickel market.
What is the cheapest form of Inconel 718?
Large-diameter black hot-rolled round bar in mill quantities is usually the lowest-cost form. Additive-manufacturing powder is the most expensive because of atomization, screening, and certification costs.
Does Chinese Inconel 718 meet AMS specifications?
Yes, provided the supplier has the correct melt practice, heat treatment, testing, and documentation. Many Chinese mills produce UNS N07718 / GH4169 that meets AMS 5662/5663 chemistry and mechanical requirements. Verify the supplier’s certificate and, if needed, arrange third-party inspection before shipment.
How often do Inconel 718 prices change?
Prices can change monthly because of nickel and niobium alloy surcharges. For long-term projects, request a quote validity period and ask whether the price is fixed or subject to raw-material adjustment.
