Description

TP347H Stainless Steel Pipe – High-Temperature, Corrosion-Resistant Alloy | KCM

The TP347H Stainless Steel Pipe by KCM is engineered for superior performance in high-temperature and corrosive environments. Manufactured from niobium-stabilized austenitic stainless steel, TP347H offers enhanced creep strength, thermal stability, and resistance to intergranular corrosion—making it suitable for continuous operation in environments up to 1000°C.

This pipe is ideal for boiler tubes, superheaters, reheaters, heat exchangers, and chemical processing systems where oxidation resistance and structural integrity are critical. The stabilizing element (niobium) prevents carbide precipitation at grain boundaries during high-temperature exposure, ensuring long-term resistance to sensitization and corrosion.

Available in a wide range of sizes and wall thicknesses, KCM’s TP347H pipes are precision-engineered, dimensionally accurate, and compliant with international standards, delivering reliable performance in demanding industrial environments.
