Stainless steel Approximately 15% chromium and 5% nickel make up 15-5 PH Bars, which are martensitic precipitation-hardening stainless steels with trace amounts of copper and niobium added for strength. Particularly under heat-treated conditions like H900 or H1025, this alloy exhibits exceptional mechanical qualities, such as high yield strength and tensile strength up to 1380 MPa. In mild and chloride-containing environments, it offers good corrosion resistance and enhanced toughness over 17-4 PH. Because of its refined microstructure, 15-5 PH also has excellent transverse mechanical properties and can be readily machined and welded after heat treatment.
