ASTM A213 T22 Seamless Ferritic Alloy-Steel Boiler Tubes
Standard:ASTM A213/ASME SA213
Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
ASTM A213 T22 Steel
A213 T22: "A" is the mark of ASTM steel material. "213" refers to the code sequence number, "T22" refers to the steel grade classification, "t" refers to small diameter pipe, equivalent to 12CR2MOG small diameter pipe in China.)
A213 T22 is a chrome molybdenum high temperature ferritic steel for boiler and superheater with ASTM A-213 / A-213m standard steel grade of 2.25Cr-lMo. It was transplanted to GB5310 in 1985 and named 12CR2MOG. Other countries also have similar steel grades, such as 10CrMo910 in Federal Germany and stba24 in Japan. In the CR -1Mo steel series, its thermal strength performance comparison draft; at the same temperature (temperature ≤ 580 ℃), its creep fracture strength and allowable stress are even higher than that of 9Cr - 1Mo steel; moreover, it has good processability, weldability and durable plasticity. Therefore, it has been widely used in the harsh working environment, such as various heating pipes and high-pressure vessels in thermal power, nuclear power and some hydrogen generating equipment.
