Ojas Pipes and Tubes stands out as a trusted manufacturer and supplier of Stainless Steel 317 and 317L ERW Pipes in Kolkata, India. We specialize in delivering top-notch welded piping solutions designed for corrosive and high-temperature settings. SS 317 and 317L are austenitic stainless steels enriched with molybdenum, which gives them exceptional resistance to pitting and crevice corrosion. Our ERW (Electric Resistance Welded) pipes are crafted in line with international standards like ASTM A312 and ASTM A269, ensuring they boast excellent dimensional accuracy and weld integrity. Perfect for chemical processing, pharmaceuticals, and marine applications, Ojas guarantees pipes that consistently deliver quality and reliable performance.
SS 317 and 317L ERW Pipes are composed of Chromium (18–20%), Nickel (11–15%), and a higher Molybdenum content (3–4%), which significantly boosts their corrosion resistance in chloride-heavy environments. The carbon content is kept to ≤0.08% in 317 and ≤0.03% in 317L, enhancing weldability and minimizing carbide precipitation. These pipes exhibit impressive mechanical properties, with a tensile strength ranging from 515 to 750 MPa, yield strength between 205 and 275 MPa, and elongation of up to 40%. They maintain outstanding strength and corrosion resistance even at elevated temperatures, making them perfect for demanding industrial and marine conditions.
