317L Stainless Steel Pipes and Tubes is molybdenum bearing austenitic stainless steel similar to 316, but with higher molybdenum alloy content. It is also known as UNS S31703 Pipes and Tubes, and is primarily comprised of 18% to 20% chromium and 11% to 15% nickel.
Stainless Steel 317L Pipes and Tubes offer higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels.
SS 317L Pipes is a low carbon grade which provides resistance to sensitization during welding and other thermal processes. Stainless Steel 317L Pipes & Stainless Steel 317 Tubes has excellent corrosion resistance and is used mainly in high acidic chloride media, such as those encountered in pulp and paper mills. Our WNR 1.4438 Seamless Tubing are primarily used in manufacturing flue gas desulfurization systems, textile equipment, chemical and petro-chemical processing equipment, pulp and paper plants, food processing equipment and textile equipment.
