422 Stainless Steel

422 martensitic stainless steel is an AOD + ESR melted grade with additional heavy metal alloying elements giving it good strength and temper resistance at higher temperatures up to 1200oF.  Similar to the 410 stainless this grade has the ability to be heat treated to multiple different strength levels.  Because of the temper resistance this alloy is often used in the power generation market as steam and gas turbine components or various other high heat components.
