GH4738 is a Ni-Cr-Co based precipitation hardened superalloy.

 

GH4738 has higher yield strength and fatigue resistance during 760°C~870°C.It has good oxidation resistance and corrosion resistance in a gas turbine atmosphere at 870 degree C.It has good ductility and stable properties. It is suitable for making turbine disk, working blade, high temperature fastener, flame tube, shaft and turbine brake.
