Harsh Metalloys stands out as a top manufacturer and supplier of Stainless Steel 15-5 PH Bars, proudly based in Mumbai, India. This particular grade, known as SS 15-5 PH (UNS S15500), is a precipitation-hardening martensitic stainless steel that boasts impressive strength, outstanding corrosion resistance, and solid transverse toughness. It’s an upgraded version of 17-4 PH, featuring enhanced toughness and lower ferrite content. Harsh Metalloys offers these bars in a range of diameters and heat-treated conditions like H900, H1025, and H1150M, all in line with international standards such as AMS 5659 and ASTM A564. These bars are perfect for applications in aerospace, marine, chemical, and high-stress mechanical fields.
When it comes to composition and mechanical properties, Stainless Steel 15-5 PH Bars generally consist of 15% chromium, 5% nickel, and trace amounts of copper (around 3.5%), manganese, silicon, and carbon. This alloy can achieve a tensile strength of up to 1310 MPa, a yield strength of about 1170 MPa, and an elongation rate of 10–15%, depending on the aging treatment applied. With a hardness reaching up to 40 HRC, SS 15-5 PH is not only machinable and weldable but also exhibits excellent mechanical properties in both longitudinal and transverse directions. Additionally, it offers remarkable resistance to stress corrosion cracking and general corrosion, making it an ideal choice for precision-engineered, high-strength components.
