GH738 is a nickel-based superalloy strengthened by γ' phase precipitation. It has good gas corrosion resistance, high yield strength and fatigue property, good process plasticity and stable microstructure. Widely used in aero-engine rotating parts, the operating temperature is not higher than 815ºC. Can produce cold rolled and hot rolled sheet, pipe, strip, wire and forgings, castings, fasteners.
