Harsh Metalloys is a reputable manufacturer and supplier of Stainless Steel 17-7 PH Coils, located in Mumbai, India. These coils are crafted from a precipitation-hardening stainless steel alloy (UNS S17700), celebrated for its remarkable strength, hardness, and resistance to corrosion. The 17-7 PH stainless steel is particularly ideal for applications that demand exceptional mechanical properties and stability under thermal stress. Harsh Metalloys offers 17-7 PH coils in a variety of thicknesses, widths, and tempers, ensuring optimal performance across sectors like aerospace, automotive, petrochemical, marine, and industrial equipment, all while adhering to international quality and testing standards such as ASTM A693.
Stainless Steel 17-7 PH Coils are composed of about 17% chromium and 7% nickel, with aluminum (0.75–1.5%) added to facilitate precipitation hardening. They boast a tensile strength of up to 1380 MPa and a yield strength of at least 1170 MPa, along with impressive hardness and fatigue resistance, particularly in heat-treated conditions like TH1050 and RH950. These coils maintain high strength and excellent corrosion resistance at temperatures reaching 600°F (316°C). Additionally, 17-7 PH offers good formability and minimal distortion during heat treatment, making it perfect for components that require precise dimensional tolerances and structural integrity.
