Age-hardenable Ni-Cr-Fe superalloy with outstanding tensile, fatigue, creep & rupture strength from -423°F to 1300°F.
Inconel 718 (also known as Alloy 718) is a high-strength, corrosion-resistant, age-hardenable nickel-chromium-iron-molybdenum alloy designed for demanding service from -423°F to 1300°F. It is well known for excellent tensile strength, fatigue resistance, creep strength, and rupture strength at elevated temperatures. In addition, Alloy 718 provides strong resistance to oxidation and aqueous corrosion, making it a reliable choice for critical components in harsh industrial environments.
