Stainless Steel 422 is a high-chromium, hardenable martensitic stainless steel alloyed with molybdenum, tungsten, and nickel for enhanced high-temperature strength. The alloy offers excellent tensile and yield strength, especially after heat treatment, along with reliable toughness and good creep resistance. SS 422 maintains its mechanical stability under prolonged exposure to elevated temperatures and provides moderate corrosion resistance in mildly corrosive environments. Its hardenability allows it to achieve superior wear and fatigue resistance. These properties make Stainless Steel 422 a reliable choice for components exposed to continuous thermal stress and mechanical load.
