1. Introduction to Inconel X-750 Materials
Inconel X-750 alloy is a nickel-based superalloy strengthened by aging precipitation of γ” [Ni3(Al, Ti, Nb)] phase. It boasts good corrosion and oxidation resistance below 980°C, high tensile strength under 800°C, outstanding stress relaxation resistance below 540°C, as well as excellent formability and weldability. This alloy is mainly used for flat springs and coil springs serving below 800°C requiring high strength, and also turbine blades and other components. Available product forms include plates, strips, bars, forgings, rings, wires and seamless pipes.
