17-4 PH is a martensitic, precipitation-hardening stainless steel that provides an outstanding combination of high strength and hardness along with excellent corrosion resistance. 17-4 PH has good fabricating characteristics and can be age hardened by a single step, low temperature treatment. 17-4 PH is a versatile material widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.
17-4 PH Stainless Steel withstands corrosive attack better than any of the standard hardenable stainless steels and is comparable to Type 304 in most media.
In Condition A, 17-4 PH is hard, therefore forming normally should be limited to mild operations. However, formability can be greatly improved by heat treating before cold working or by use of hot-forming methods.
