ASTM A213 Alloy Seamless Steel Pipe

Publisher:TianchengTime:2018-07-02Number:136

ASTM A213 Alloy Seamless Steel Pipe
ASTM A213 covers seamless ferritic and austenitic steel boiler,Boiler Tube, and heat-exchanger tubes for high temperature services, designated Grades T5, TP304, etc. Grades with letter H has highe creep-rupture strength compared with grades with no H. ASME SA213 seamless tubes are chrome moly Tubes with alloy element of chromium, molybdenum.Tiancheng Group is one of the manufacturer and supplier of ASTM A213 Low Alloy Steel Tubes of all grades and dimensions. We also keep stock of ASTM A213 seamless tubes of Alloy Steel:T2, T11, T12, T22, T91, T92in annealed and pickled, bright annealed, mill finish and polished conditions according to customer requirements.
