GB 5310 10Cr9Mo1VNbN boiler steel pipe

GB 5310 10Cr9Mo1VNbN boiler steel pipe Chemical Composition and Mechanical Property

GB 5310 10Cr9Mo1VNbN boiler steel pipe has not only high oxidation resistance and high temperature steam corrosion resistance, but also good impact toughness, high and stable durability and thermal strength. When the temperature is below 620 C, the applied stress of GB 5310 10Cr9Mo1VNbN boiler steel pipe is higher than that of austenitic stainless steel. The recommended design stress is about two times of T9 and 2.25Cr-1Mo steel at temperatures above 550 C.
