ASTM A269 TP 317L WELDED TUBES

ASTM A269 TP 317L Welded Tubes

ASTM A269 TP 317L Welded Tubes are high-performance austenitic stainless steel tubes engineered for superior corrosion resistance in aggressive environments. Manufactured using premium TP 317L stainless steel, these welded tubes offer excellent resistance to pitting, crevice corrosion, and chemical attack, especially in chloride-containing media.

TP 317L is a low-carbon, high-molybdenum stainless steel grade that provides enhanced corrosion resistance compared to conventional 316L. The increased molybdenum content significantly improves resistance to localized corrosion, while the low carbon composition minimizes the risk of intergranular corrosion after welding. ASTM A269 TP 317L Welded Tubes are widely used in chemical processing, petrochemical, pulp & paper, pharmaceutical, and marine applications.
