**Stainless Steel 15-5 PH** is a precipitation-hardening martensitic stainless steel celebrated for its remarkable mechanical properties and resistance to corrosion. Typically, it contains **15% Chromium, 5% Nickel**, along with **Copper** to facilitate age hardening. This alloy boasts **tensile strengths reaching up to 1380 MPa**, impressive yield strength, and outstanding toughness—especially in the transverse direction. It comes in various heat-treated conditions (like H900 to H1150), allowing it to cater to specific application requirements. Additionally, it’s weldable and shows minimal distortion during heat treatment, making it perfect for components that demand dimensional stability and consistent strength.
