17-4 PH steel (AMS 5604) is a grade of martensitic, precipitation-hardening stainless steel with the additions of chromium, nickel, and copper. 17-4 stainless steel has a valuable combination of high strength, good corrosion resistance, and toughness in both base metals and welds. This material provides excellent corrosion resistance (comparable to grade 304) for many medical, chemical, paper, and food processing industries, and it withstands corrosive attacks better than most hardenable stainless steels.
These properties give designers the ability to add reliability to their products while simplifying fabrication and often reducing their costs. High strength is maintained to approximately 600°F (316°C). 17-4ph has good resistance to stress corrosion cracking at higher aging temperatures.

Also known as Alloy 630, type 17-4PH is the most widely used of all precipitation-hardening steels. Compared to other PH alloys, it requires a simple heat treatment to produce a wide range of properties, including its high strength. It has a slightly higher ferrite content than other PH grades, making it a bit more magnetic. To improve formability, heat treatments may be used before cold working.
