Type 422 (S42200) is a hardenable martensitic stainless steel offering superior strength at high temperatures, serving as an appealing alternative to Type 403. It can be heat-treated to various high-strength levels and is widely used in the aircraft and power industries where high strength-to-weight ratios are required from room temperature up to 1200°F.
