GH4090 is a deformed superalloy with Ni-Cr-Co base precipitation hardening type. The GH4090 can operate at temperatures up to 920. At 815-870 temperature, it has high tensile strength, creep resistance, good resistance to Yang and corrosion resistance, and high PI strain degree under the repeated action of cold and heat. The GH4090 has good machining and welding properties. Suitable for making aero turbine engine vortex Lun disk, blade, high temperature fasteners, clamps, sealing rings and elastic elements.
