GH90 is an aging-strengthened nickel-based deformed high-temperature alloy, which contains a relatively high amount of cobalt and a variety of strengthening elements. The alloy has high tensile strength and creep resistance at 815~870ºC, good oxidation resistance and corrosion resistance, high fatigue strength under repeated alternating effects of cold and heat, and good formability and welding. Sex. Mainly supply hot-rolled and cold-drawn bars, cold-rolled plates, strips and cold-drawn wires. Used for turbine discs, blades, high temperature fasteners, clamps, sealing rings and elastic components of turbine engines.
