Alloy 422 is a hardenable stainless steel designed for use at temperatures of up to 1200ºF (649ºC). Alloy 422 has good resistance to scaling and oxidation. Through heat treatment, high mechanical properties can be developed. Alloy 422 is used in applications such as compressors or steam turbines and also in aircraft parts, valves, high temperature bolting etc.
