Stainless Steel 17-4 PH is a type of precipitation-hardening martensitic stainless steel that contains about 17% chromium, 4% nickel, and 3–5% copper, along with trace amounts of niobium and tantalum. This specific composition enables it to achieve remarkable strength and hardness through heat treatment, with tensile strengths ranging from 930 to 1400 MPa and yield strengths from 860 to 1300 MPa. The material also showcases good corrosion resistance and hardness levels up to 44 HRC, making it a great fit for wear-resistant applications while still maintaining moderate ductility and toughness.
