Harsh Metalloys is a trusted manufacturer and supplier of Stainless Steel 317L Pipes in Mumbai, India, delivering superior corrosion-resistant piping solutions to a wide range of industries. SS 317L is a low-carbon, molybdenum-bearing austenitic stainless steel grade offering enhanced resistance to chemical attack, especially in acidic and chloride-rich environments. These pipes are available in seamless, welded, ERW, and EFW forms, conforming to ASTM A312, A358, and other international standards. Known for their high strength, excellent weldability, and long service life, 317L stainless steel pipes are ideal for critical applications in pharmaceutical, chemical processing, food, and marine .
Stainless Steel 317L Pipes are alloyed with 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with a reduced carbon content (max 0.03%) to prevent carbide precipitation during welding. This composition enhances resistance to pitting, crevice corrosion, and general chemical attack. These pipes exhibit a minimum tensile strength of 515 MPa and a yield strength of 205 MPa, with excellent elongation and ductility. The low carbon version ensures improved intergranular corrosion resistance after welding, making SS 317L suitable for pressure and high-temperature applications without loss of strength or corrosion resistance.
