GH90(4090)
GH90 is a NI-CR-CO-based precipitation hardening deformed high-temperature alloy with a service temperature of up to 920°C. Containing a relatively high amount of cobalt and a variety of strengthening elements, the alloy has high tensile strength and creep resistance at 815 to 870°C, good oxidation resistance and corrosion resistance, and has greater resistance to cold and heat under repeated alternating effects. High fatigue strength and good processing and welding properties.
