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.
