With additions of molybdenum, tungsten, and vanadium to improve strength and heat resistance, Stainless Steel 422 is a hardenable martensitic stainless steel alloy that contains roughly 11.0–13.0% chromium and 0.20–0.25% carbon. With a yield strength of about 415 MPa and a tensile strength range of 655–965 MPa, this alloy can be heat treated to achieve high strength and hardness. At temperatures as high as 1200°F (649°C), it provides outstanding resistance to creep and oxidation while retaining good toughness. In harsh operating conditions, stainless steel 422 offers dependable mechanical performance and is magnetic.
