Not only has high oxidation resistance and corrosion resistance of high temperature steam, but also has good impact toughness and high and stable strong durable plastic and thermal properties. In the use of temperatures lower than 620 ℃, the allowable stress is higher than austenitic stainless steel. At 550 ℃ for more than the recommended allowable design stress about T9 and 2.25Cr-1Mo steel double.
Applications:
\ Can be used as sub-critical, supercritical boiler wall temperature ≤ 625 ℃ high temperature superheater, reheater uses steel, as well as the wall temperature ≤ 600 ℃ high temperature and steam header piping, heat exchangers can also be used as nuclear power and oil cracking furnace tube device.
