SA-210C is the ASME standard steel grade, which belongs to the category of medium carbon manganese steel pipes for boilers, superheaters and pipes. It is a pearlitic type heat-strength steel. "SA" is the mark of ASME steel materials. "210" represents the specification sequence number, and "C" represents the strength level, which is similar to the composition and performance of my country's 25MnG steel small-diameter steel pipe.
SA-210C has good hot and cold processing performance and welding performance; SA-210C is widely used in water-cooled walls, economizers, low-temperature superheaters and other heating surface piping systems of large-capacity power station boilers such as 300MW and 600MW where the operating temperature is lower than 500°C. And headers, soda and water pipes, etc.
standard:
ASTM A210 / A210M/ ASME SA-210 / SA-210M
use:
It is suitable for boiler tubes and boiler flue tubes, including safety ends, vaults and support tubes, as well as small wall thickness seamless medium carbon steel tubes for superheater tubes.
