ASTM A376 TP347H seamless pipes are high-temperature austenitic stainless steel tubes stabilized with niobium (Nb). Engineered for superior creep resistance and oxidation resistance up to 815°C (1,500°F), they withstand extreme thermal cycling and corrosive environments. Compliant with ASTM A376 standards, these pipes are solution-annealed for optimal microstructural stability, making them ideal for critical high-pressure applications.
The niobium-stabilized chemistry prevents chromium carbide precipitation, enhancing intergranular corrosion resistance.
