UNS N07750

UNS N07750 alloy is mainly a nickel-based high-temperature alloy strengthened by aging with γ′[Ni3(Al, Ti, Nb)] phase. It has good corrosion resistance and oxidation resistance below 980℃, high strength below 800℃, good relaxation resistance below 540℃, and good forming and welding properties. This alloy is mainly used to manufacture aero-engine parts such as rings, structural parts and bolts that require high strength and corrosion resistance and work below 800℃, and plane springs and spiral springs that work below 540℃ with medium or low stress and require relaxation resistance. It can also be used to manufacture parts such as turbine blades of gas turbines. Available varieties include plates, strips, bars, forgings, rings, wires and pipes.
