Stainless Steel 17-4PH forgings consist of a precipitation-strengthening martensitic stainless steel alloy with around 17% chromium and 4% nickel, as well as trace amounts of copper, manganese, and niobium. The above composition provides the alloy with outstanding strength, hardness, and resistance to corrosion. Its mechanical properties are tensile strength as high as 1100 MPa, yield strength around 1000 MPa, and hardness ranging from HRC 28-44, which is heat treatment dependent. This renders Stainless Steel 17-4PH forgings suitable for high-stress applications that demand strength and corrosion resistance.
