A good performance and welding process performance, in the 500 ~ 550 ℃ under sustained high intensity. Temperature exceeds 550 ℃, the oxidation resistance variation, a significant reduction in creep strength. Long-term at 500 ~ 550 ℃, the strong heat of steel decreased degradation. 510 ℃ for the manufacture of high, medium pressure steam conduit, as well as the header wall temperature of 550 ℃ and the forging of the superheater.
