Stainless Steel 17-7 PH is a precipitation-hardened alloy that contains about 17% chromium and 7% nickel, along with trace amounts of aluminum and manganese. This unique composition gives it impressive tensile and yield strength through heat treatment, along with excellent fatigue resistance and decent corrosion resistance. Typical mechanical properties include a tensile strength of up to 1310 MPa, a yield strength around 1170 MPa, and an elongation of 6–10%. It remains stable and strong even at high temperatures, while also being fairly easy to form and machine, making it a go-to choice for high-performance structural and mechanical components.
