ASME SA213 TP347H is a niobium-stabilized austenitic stainless steel designed for elevated temperature service in ultra-supercritical (USC) boiler superheaters and reheaters. The niobium stabilization prevents chromium carbide precipitation during welding and high-temperature operation, ensuring superior resistance to intergranular corrosion and sensitization.
