15crmog Boiler Tube

15CrMo steel is widely used in the power industry and has high heat resistance at 500 ° C - 550 ° C. When the use temperature is greater than 550 ° C, 15crmog thermal strength is significantly reduced. Generally, 15CrMo steel is mainly used for high and medium pressure pipes and steam pipes with a steam parameter of 510 ° C, and heat pipe with a wall temperature of 550 ° C.

The same type of steel abroad, including the former Soviet Union's 15XM, the US brand T12, P12, the Japanese brand STBA22, STPA22 and the German brand 13CrMo44.
