ASTM A213 Alloy Steel Pipe
ASTM A213 is a widely recognized standard that specifies seamless ferritic and austenitic steel pipes used for high-temperature applications, such as boiler tubes, superheater tubes, and heat exchanger tubes. The standard includes various grades like T5, TP304, and others. Grades with the letter "H" are specifically designed to offer improved creep rupture strength compared to their non-H counterparts. ASME SA213 refers to the same material specifications, often used in pressure vessel and piping systems where chromium-molybdenum alloys are required for enhanced performance at elevated temperatures.
CSC STEEL is a leading manufacturer and supplier of ASTM A213 low alloy steel pipes, offering a wide range of grades and sizes tailored to meet specific industrial needs. Our inventory includes seamless pipes in grades such as T2, T11, T12, T22, T91, and T92, available in different conditions like annealed and pickled, bright annealed, or finished and polished, depending on customer requirements. These pipes are ideal for use in power generation, petrochemical, and other high-temperature environments where durability and reliability are critical.
