Nimonic90 is a Ni-Cr-Co based precipitation hardening deformation superalloy, and its service temperature is 920℃. The alloy has high tensile strength, creep resistance, good oxidation resistance and corrosion resistance at 8 15℃-870℃, high fatigue strength and good machining and welding performance under the repeated alternating action of cold and hot. It is suitable for manufacturing turbine turntables, blades, high-temperature fasteners, fixtures, sealing rings and elastic parts of aviation turbine engines. The main products are hot-rolled bars, cold-drawn bars, cold-rolled plates, strips and cold-drawn materials.
The alloy has been used to manufacture high-temperature spring elements, high-temperature fasteners, combustion chamber collars and stop pins of aero-engines. In foreign countries, similar brands are also used to manufacture aero-engine turbine blades, turbine turntables and other parts.
The alloy has good oxidation resistance and corrosion resistance below 1040℃, and intergranular oxidation is easy to occur above 1040℃.
