ASTM A213 TP 317L WELDED TUBES

ASTM A213 TP317L Welded Tubes

ASTM A213 TP317L Welded Tubes are high-performance austenitic stainless steel tubes engineered for superior corrosion resistance and high-temperature service applications. Manufactured using premium quality TP317L stainless steel, these welded tubes provide excellent resistance to pitting, crevice corrosion, and chemical attack in aggressive environments.

TP317L is a low-carbon, high molybdenum stainless steel grade that offers improved corrosion resistance compared to conventional 316L stainless steel. The increased molybdenum content enhances resistance to chloride-induced corrosion, while the low carbon composition minimizes the risk of intergranular corrosion after welding. ASTM A213 TP317L Welded Tubes are widely used in chemical processing, petrochemical, pulp & paper, power generation, and marine industries.
