Chemical Composition & Physical Performance of SA-210C
Feb 09, 2018

      SA-210C is the steel gade of ASME standard, which is for boiler, superheater and carbon manganese steel pipe, it belog to pearlite type refractory steel. So SA210C is not stainless steel. In 1995, China transplanted it to GB5310 seamless steel pipe for high pressure boiler standard, named 25MnG. But it make more clearly limit to the content range of C and Mn. The density of steel SA210C is 7.85, it widely used in 300MW, 600MW and other large capacity power station boilers, which temperature less than 500 degrees centigrade water cooled wall, economizer, low temperature overheater, and other heating surface piping and header, steam & water pipe etc.
