Product Overview – ASTM A213 TP317L Seamless Tubes
ASTM A213 TP317L seamless stainless steel tubes are low-carbon, high-molybdenum austenitic tubes designed to provide exceptional resistance to corrosion in aggressive industrial environments.
The reduced carbon content improves weldability and prevents carbide precipitation during welding, making TP317L an ideal choice for fabrication-intensive industries.
Compared with standard 316L tubes, TP317L offers enhanced resistance to pitting, crevice corrosion, and chemical attack due to its higher molybdenum content.
Manufactured through hot finished or cold drawn seamless processes, these tubes ensure high dimensional accuracy, superior mechanical strength, and excellent pressure handling capability.
ASTM A213 TP317L seamless tubes are widely used in heat exchangers, chemical plants, pulp and paper processing units, marine engineering systems, and pollution control equipment where corrosion resistance is critical.
