ASTM A213 T2 Alloy Steel Seamless Tubes
Description
ASME SA213 T2 Seamless Steel Tubes
SA213 T2 is the steel grade in ASME SA213M standard. It is a 1 / 2cr-1 / 2Mo type steel developed on the basis of 1 / 2Mo steel. It is a ferritic hot strength steel for boiler and superheater.
SA213 T2 steel is close to 12CrMoG of GB5310 in China. Because the steel contains chromium, which can prevent the tendency of graphitization, after long-term use at 480-540 ℃, the mechanical properties and microstructure are stable enough, and the pipe processing and welding properties are good.
