17-4PH Stainless Steel Bar (AMS 5643/ AMS 5622)


Technical Data Sheet

17-4PH  is a martensitic, precipitation-hardening stainless steel that provides an outstanding combination of high strength and hardness along with excellent corrosion resistance. 17-4PH has good fabricating characteristics and can be age hardened by a single step, low temperature treatment. 17-4PH is a versatile material widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.
