AISI 422 UNS S42200 Alloy 422 Grade 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. It is high-alloy steels that exhibit better corrosion resistance than other steels and this is because of the increased chromium content. It is often used in aircraft parts, refineries, thermal pipe plants, high heat components, pharmaceutical industry, oil refineries, textile industries, rotors, nuclear plants, chemical industrries and power industries where high strength ratios is required.
