Our 17-4 PH Stainless Steel (SS) is a precipitation hardening martensitic stainless steel. Typical 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. Best Stainless offers high quality standards including: UNS S17400, AMS 5643, ASTM A564, and ASTM A693 Grade 630.

17-4 PH Stainless steel can be used for a variety of industires including: pump shafts, oil path, mechanical seals. Its composition is carbon, chromium, columbian + tantalum, copper, manganese, nickel, phosphorous, silicon, and sulfur.

Below you will find typical applications of 17-4 PH stainless steel as well as the metals composition and mechanical properties.
