ASME SA213 S30432 SUPER 304H seamless steel pipe
SA213 S30432 (super 304H) steel tube is a new type of 18-8 austenitic stainless steel tube, which is mainly used to manufacture superheater and reheater of ultra supercritical boiler with metal wall temperature not exceeding 700 ºC.
SA213 S30432 (super 304H) steel reduces Mn content on the basis of TP304H, adds 3% Cu, 0.45% Nb and a certain amount of N, which makes the steel produce dispersion precipitation phase and copper rich strengthening phase in service, and copper rich phase together with NBC (n), nbcrn and M23C6 produces excellent precipitation strengthening effect, which greatly improves the allowable stress under service temperature. The allowable stress at 600-650 ºC is 30% higher than that of TP347H steel. Compared with tp347hfg steel, the steam oxidation resistance of this steel is better than that of tp321h steel. It has been listed in ASME code 2328-1, ASTM A213 and GB 5310-2008 standards, and its grades are S30432 and 10cr18ni9nbcu3bn respectively
