15-5PH is a martensitic stainless steel containing about 15% chromium and 5% nickel with additions of copper. It is a precipitation hardening stainless steel that has the same properties as its original predecessor 17-4PH. Precise control of the melting and subsequent forming process results in a unique structure that contributes to increased toughness and ductility of the alloy compared to 17-4PH. In many corrosive environments, its resistance is better than that of 410 stainless steel and comparable to that of 302 and 304 stainless steels. Because of this combination of mechanical properties and corrosion resistance, 15-5PH is used in a wide range of applications.
