Medical422 Annealed is a hardenable martensitic stainless steel which is being widely used for high temperatures up to 1200F. It is capable of being heat treated to various high strength levels. The material is ideal for products that require high strength/weight ratios from room temperature to 1200F. Adaptable to applications where maximum resistance to corrosion is not required. Resistant to the corrosive action of the atmosphere, fresh water, steam, and a variety of the milder acids and alkalies. Grade 422 is often used to produce Aircraft Parts, Steam & Gas Turbine Components, High Heat Components and Rotors. (UNS S42200)
