Martensitic, precipitation-hardened stainless steel alloys with 14–15.5% chromium, 3.5–5.5% nickel, and roughly 0.15–0.45% copper make up stainless steel 15-5 PH bars. Depending on the heat treatment condition (H900, H1025, etc.), these bars have exceptional mechanical qualities with a tensile strength of up to 1,310 MPa, a yield strength of about 1,100 MPa, and an elongation of roughly 10–15%. Compared to 17-4 PH, SS 15-5 PH shows better corrosion resistance and transverse toughness. It is perfect for demanding load-bearing applications because of its uniform mechanical properties, which are guaranteed by its controlled chemical composition.
