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.
|Weight(%)||0.003~0.010||0.020~0.080||0.10 max||0.015 max||0.015 max||0.015 max||0.100 max|
The alloys have good oxidation resistance and corrosion resistance in various atmospheres encountered in jet engines or similar working conditions. Continuous operation of the antioxidant temperature up to 1040°C. Intermittent operation of the antioxidant temperature up to 870°C.
