What is Inconel 718?
Inconel 718 (UNS N07718) is a high-nickel-based superalloy known for its exceptional high strength, high-temperature oxidation resistance, and corrosion resistance. It is widely used in high-end manufacturing fields such as aircraft engines, gas turbines, energy equipment, chemical machinery, and nuclear power. Due to its superior performance, Inconel 718 typically commands a price significantly higher than conventional stainless steel and base metals.

Inconel 718 is a high-value nickel-based superalloy, and its price per kg is driven by nickel market volatility, processing complexity, certification level, and supply–demand dynamics. For procurement managers, understanding what really drives the price-not just the quoted number-is critical to controlling project cost and supplier risk.
In 2025, the typical Inconel 718 price per kg ranges from USD 40 to USD 120, depending on form, quality grade, and order volume. Aerospace-certified or precision-processed material can exceed this range.
Inconel 718 Price per Kg (2025)
| Product Form | Typical Price (USD/kg) | Procurement Notes |
|---|---|---|
| Hot-rolled plate / bar | 40 – 70 | Industrial grade, mill standard |
| Cold-finished bar | 55 – 90 | Higher dimensional accuracy |
| Aerospace-certified material | 80 – 120+ | AMS / ASTM full traceability |
| Forgings / custom sizes | 90 – 150+ | Tooling & processing cost included |
| Powder / additive grade | 120 – 300+ | Specialized production routes |
Important:Small-quantity purchases, tight tolerances, or urgent delivery can increase the effective price per kg by 20–40%.
Key Factors Affecting the Price of Inconel 718
Nickel Price Fluctuations (Major Cost Driver)
Nickel accounts for more than half of the alloy's composition; therefore, the price of Inconel 718 is highly sensitive to global nickel price fluctuations. When nickel prices rise, raw material surcharges are usually passed directly on to buyers.
Purchasing Recommendation: Signing long-term contracts or using price-locking mechanisms can significantly reduce the risks associated with nickel price fluctuations.
