Product details

17-4PH Stainless Steel Bar

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 industries including pump shafts, oil path, mechanical seals, and within the aerospace industry. Its composition is carbon, chromium, columbian + tantalum, copper, manganese, nickel, phosphorous, silicon, and sulfur.
