Inconel 718 sheet is a high-value nickel-based superalloy flat product, primarily used in aerospace, energy, oil & gas, and high-temperature structural applications.Unlike commodity metals, the price per ton of Inconel 718 sheet reflects performance reliability, certification level, and processing complexity, not just raw material cost.
In 2025, the typical Inconel 718 sheet price per ton ranges from USD 40,000 to USD 110,000, depending on thickness, surface condition, heat treatment, certification, and order volume.
Inconel 718 Sheet Price per Ton (2025 Market Range)
| Sheet Type | Thickness Range | Typical Price (USD/ton) |
|---|---|---|
| Hot-rolled sheet / plate | ≥6.0 mm | 40,000 – 65,000 |
| Cold-rolled sheet | 0.8 – 5.0 mm | 55,000 – 85,000 |
| Aerospace-certified sheet | 0.5 – 4.0 mm | 75,000 – 110,000+ |
| Precision or custom-cut sheet | Any | 90,000 – 130,000+ |
What is Inconel 718 plate?
Inconel 718 (UNS N07718 / W.Nr. 2.4668) plate is a precipitation-hardened nickel-chromium alloy flat product, supplied in hot-rolled or cold-rolled form, suitable for aerospace structural panels, gas turbine components, heat shields, and high-stress supports, and high-temperature chemical equipment.
Reasons why buyers choose GNEE Inconel 718 plate: Yield strength exceeding 1000 MPa, excellent fatigue and creep resistance at temperatures up to approximately 700°C, good weldability compared to many high-temperature alloys, and stable mechanical properties in both thick and thin sections.
