ASTM A213 Alloy Steel Pipe
ASTM A213 covers seamless ferritic and austenitic steel boilers, boiler tubes and heat exchanger tubes for high temperature applications, with designated grades T5, TP304, etc. Grades with the letter H have higher creep rupture strength than grades without the H. ASME SA213 seamless pipe is a chromium-molybdenum pipe containing chromium and molybdenum alloy elements.
CSC STEEL is one of the leading manufacturers and suppliers of ASTM A213 Low Alloy Steel Pipes in various grades and sizes. We also stock ASTM A213 alloy steel seamless pipes: T2, T11, T12, T22, T91, T92 in annealed and pickled, bright annealed, finishing and polished conditions as per customer requirements.
