ASTM A213 Alloy Steel Pipe
ASTM A213 specifies seamless ferritic and austenitic steel pipes and tubes designed for use in high-temperature environments, such as boilers, heat exchangers, and other critical components. The standard includes various grades like T5, TP304, and more. Grades marked with the letter "H" exhibit enhanced creep rupture strength compared to those without the "H." ASME SA213 seamless pipes are typically made from chromium-molybdenum alloys, which provide excellent resistance to high temperatures and corrosion.
CSC STEEL stands out as a premier manufacturer and supplier of ASTM A213 low-alloy steel pipes in diverse grades and dimensions. We maintain an extensive inventory of ASTM A213 alloy steel seamless pipes, including grades T2, T11, T12, T22, T91, and T92. These pipes are available in various conditions such as annealed and pickled, bright annealed, finished, and polished, tailored to meet specific customer requirements.
