What is the ASTM A213 Steel Tube?
ASTM A213 steel tube covers seamless ferritic and austenitic steel boilers, Boiler tubes, and heat-exchanger tubes for high-temperature services, designated Grades T5, T11 T22 T9, etc. Grades with the letter H has higher creep-rupture strength compared with grades with no H. ASME SA213 seamless steel tubes are chrome moly Tubes with alloy element of chromium, and molybdenum. We also keep stock of ASTM A213 seamless tubes of Alloy Steel: T2, T11, T12, T22, T91, and T92 in annealed and pickled, bright annealed, mill finish, and polished conditions according to customer requirements.
