Product description and application

InconelX-750 alloy is mainly a nickel-based superalloy aged and strengthened by γ '[Ni3(Al, Ti, Nb)] phase. It has good corrosion resistance and oxidation resistance below 980℃, high strength below 800℃, and good relaxation resistance below 540℃. It also has good formability and weldability. The alloy is mainly used in the manufacture of aircraft engines operating below 800 ° C and require high strength corrosion resistance rings, structural parts and bolts and other parts, operating below 540 ° C with moderate or low stress and require relaxation resistance of flat springs and helical springs. It can also be used to manufacture parts such as turbine blades of air turbines. The varieties available are sheet, strip, bar, forgings, rings, wire and tubing.
