Harsh Metalloys is a reputable manufacturer and supplier of Stainless Steel 17-4 PH Coils, located in Mumbai, India. These coils are crafted from a special precipitation-hardening martensitic stainless steel alloy known as 17-4 PH (UNS S17400), which is celebrated for its impressive strength, hardness, and outstanding resistance to corrosion. 17-4 PH Coils are perfect for demanding applications where mechanical performance and protection against environmental wear are essential. Harsh Metalloys provides these coils in a variety of thicknesses, widths, and finishes, all meticulously designed to meet international standards. They are particularly suited for industries such as aerospace, nuclear, petrochemical, marine, and general engineering.
Stainless Steel 17-4 PH Coils are primarily composed of 17% chromium and 4% nickel, with additional copper (3–5%) and niobium (or columbium) to facilitate precipitation hardening. This unique alloy offers an exceptional blend of high strength and corrosion resistance. The mechanical properties can vary depending on heat treatment, but they generally include a tensile strength of up to 1100 MPa, a yield strength of at least 1000 MPa, and a hardness of up to 44 HRC. The material retains excellent mechanical strength even at elevated temperatures, reaching up to 316°C. Its well-balanced composition ensures easy machinability, good toughness, and reliable corrosion resistance in both mild and moderately aggressive environments.
