422 Stainless Steel

  • 422 Stainless Steel

     

    Stainless Steel Grade 422 is a hardenable martensitic stainless steel which is being widely used for high temperatures up to 1200°F. It has excellent creep-rupture properties in the range of 600/1200°F and is capable of being heat treated to various high strength levels depending on section, form, and application involved.

    Type 422 offers designers in the aircraft and power industries high strength/weight ratios from room temperature to 1200°F. The composition is carefully balanced to provide a microstructure which is virtually all tempered martensite after heat treatment. This structure assures uniformity of mechanical properties with a minimum of directionality.
