17-4 PH SS is a martensitic, chromium-nickel-copper precipitation-hardening stainless steel. 17-4 PH stainless steel bar is capable of attaining a wide range of strength and toughness properties depending on the precipitation or aging temperature used in hardening.  Its valuable combination of  high strength, good corrosion resistance and toughness in both base metals and welds gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. High strength is maintained to approximately 600°F (316°C). This material has good resistance to stress corrosion cracking in the lower strength conditions. Our 17-4 PH Stainless Steel is a precipitation hardening martensitic stainless steel. Typical usages are seen in the applications requires high strength and modest level of corrosion resistance. Strengthen and hardness desired can be manipulated by the temperate range in heating treatment process. Great Stainless offers high quality standards including UNS S17400, AMS 5643, ASTM A564, and ASTM A693 Grade 630. 17-4 PH stainless steel could be used for a variety of industries including pump shafts, oil path, mechanical seals, and within the aerospace industry. Its compositions are carbon, chromium, Columbian and tantalum, copper, manganese, nickel, phosphorous, silicon, and sulfur.
