ASTM A213 Alloy Steel Pipe
ASTM A213 outlines specifications for seamless ferritic and austenitic steel pipes, particularly designed for use in boilers, heat exchangers, and other high-temperature applications. Commonly used grades include T5, TP304, and others. Grades marked with an "H" typically exhibit superior creep rupture strength compared to those without the "H." ASME SA213 seamless steel pipes are chromium-molybdenum alloys that incorporate both chromium and molybdenum to enhance their mechanical properties.
CSC STEEL stands out as a premier manufacturer and supplier of ASTM A213 Low Alloy Steel Pipes in various grades and sizes. Our inventory includes ASTM A213 alloy steel seamless pipes such as T2, T11, T12, T22, T91, and T92. These pipes are available in different conditions—annealed and pickled, bright annealed, finished, and polished—to meet specific customer requirements.
