Inconel 718 plate is a versatile, high-strength nickel-based alloy known for its exceptional mechanical properties, including high tensile, yield, and creep strengths, as well as excellent resistance to oxidation, corrosion, and high-temperature creep deformation up to approximately 650°C (1200°F). The alloy's composition of nickel, chromium, iron, niobium, molybdenum, titanium, and aluminum enables it to excel in demanding applications such as aerospace, oil and gas, and hot working equipment.
At what temperature does Inconel 718 oxidize?
Inconel 718 oxidizes at a parabolic, diffusion-controlled rate over a wide temperature range of 1223 K to 1573 K in atmospheric air, lasting for weeks. Above 1573 K, oxidation becomes extremely intense, causing severe deformation.
