ASTM A312 TP 317L Pipes & Tubes are manufactured from a low-carbon austenitic stainless steel grade designed for enhanced corrosion resistance in aggressive environments. The “L” grade indicates a lower carbon content, which minimizes carbide precipitation during welding and improves resistance to intergranular corrosion. This makes TP 317L pipes and tubes especially suitable for applications requiring extensive welding and long-term service reliability..
Compared to conventional stainless steel grades such as 316L, ASTM A312 TP 317L contains higher levels of chromium, nickel, and molybdenum. This chemical composition provides superior resistance to pitting, crevice corrosion, and chemical attack in chloride-rich and acidic environments. As a result, TP 317L Pipes & Tubes are widely used in chemical processing plants, petrochemical industries, marine systems, pulp & paper mills, and pollution control equipment..
ASTM A312 TP 317L Pipes & Tubes are available in both seamless and welded forms, including ERW and EFW, to meet diverse pressure, temperature, and dimensional requirements. These products are supplied in annealed and pickled condition as per ASTM A312 / ASME SA312 standards, ensuring consistent mechanical properties, excellent surface finish, and compliance with international quality norms..
