A213 T2 Seamless Steel Tube 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.
ASTM A213 T2 Alloy Steel Seamless Tubes
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.

Oxidation resistance
SA213 T2 steel is mainly used in Superheater and reheater system with working temperature lower than 540 ℃, and its oxidation resistance is better than that of carbon steel and carbon manganese steel.
Welding performance
SA213 T2 steel has good welding performance, generally it can be annealed at 650 ~ 700 ℃ after welding without preheating. Heat 207 for manual welding rod and h12crmo / jgs-1cm for GTAW.
Tubes bending
ASME SA213 T2 seamless steel tubes are suitable for all kinds of bending processes. After cold bending, it needs to be de stressed; when the temperature of hot bending exceeds the tempering temperature, it should be re normalized and re ignited.
