About 12.5–14.5% chromium, 7.5–8.5% nickel, 0.15–0.40% carbon, and trace amounts of titanium and aluminium for precipitation hardening make up stainless steel 13-8 PH bars. This alloy has a yield strength of about 1,200 MPa, a high tensile strength of up to 1,380 MPa, and an elongation of about 8–12%. The bars have outstanding fatigue strength, good toughness, and excellent corrosion resistance. 13-8 PH bars are appropriate for demanding structural and mechanical applications because of their heat-treatable nature, which enables customised mechanical properties.
