Stainless Steel 17-4 PH

 

17-4 ph Stainless Steel is a precipitation hardening martensitic stainless steel. Typical 17-4 ph usage is seen in applications requiring high strength and a modest level of corrosion resistance. Strength and toughness desired can be manipulated by temperate range in the heat treatment process. Stainless-Steel-17-4-PH
