Description
Nimonic 90 is an age strengthened cobalt nickel base deformation superalloy. At 815 ~ 870 ℃, the alloy has high tensile strength and creep resistance, good oxidation resistance and corrosion resistance, high fatigue strength under repeated alternating action of cold and heat, and good formability and weldability. Used for turbine disk, blade, high temperature fastener, clamp, sealing ring and elastic element of turbine engine.
