ASTM A213 TP 317L Seamless Tubes

ASTM A213 TP 317L Seamless Tubes are high molybdenum austenitic stainless steel tubes engineered for superior corrosion resistance in highly aggressive environments. The increased molybdenum content compared to 316/316L enhances resistance to pitting and crevice corrosion, especially in chloride-rich conditions.

Grade 317L features low carbon content, reducing carbide precipitation during welding and providing excellent resistance to intergranular corrosion. These tubes are ideal for chemical processing, pulp and paper industries, and high-temperature applications.
