Harsh Metalloys is a trusted manufacturer and supplier of Stainless Steel 317 Pipe Fittings based in Mumbai, India, offering high-quality fittings designed for excellent corrosion resistance and strength. Stainless Steel 317 is a molybdenum-bearing austenitic alloy with a higher concentration of chromium, nickel, and molybdenum than 316-grade stainless steel, making it particularly suited for aggressive chemical environments. Our 317 pipe fittings are manufactured to meet international standards like ASTM A403 and ASME B16.9, available in various shapes such as elbows, tees, reducers, and caps. These fittings are widely used across chemical processing, petrochemicals, marine, and pollution control industries.
Stainless Steel 317 Pipe Fittings feature a chemical composition of approximately 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum carbon content of 0.08%. This composition enhances resistance to pitting, crevice corrosion, and high-temperature oxidation. These fittings offer a tensile strength of around 515 MPa and a yield strength of about 205 MPa. With superior weldability and excellent ductility, 317 fittings are ideal for complex piping systems that require long service life under corrosive and high-stress conditions. They also maintain integrity under thermal cycling and mechanical stress.
