ASTM A213 T5 Tubes | ASME SA213 T5 Seamless Boiler Tube Manufacturer & Exporter

What is ASTM A213 T5 / ASME SA213 T5 Tube?

ASTM A213 T5 is a seamless ferritic alloy steel tube made in accordance with the ASTM A213 / ASME SA213 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes. The UNS code is K41545. At high operating temperatures, its 5 Cr–0.5 Mo (chrome-moly) composition provides outstanding resistance to oxidation, creep, and thermal fatigue.

ASTM A213 T5 corresponds to ASME SA213 T5 in the ASME Boiler and Pressure Vessel Code (BPVC). SA213 is preferred when the tube is included into ASME-code pressure equipment; both classifications have the same chemical and mechanical property standards. See also ourASTM A213 T9 Tubes andASTM A213 T11 Tubes for higher-alloy alternatives.

USA Piping Solution stocks and supplies ASTM A213 Gr T5 tubes with complete mill test reports (MTRs). Our exports reach North America, Europe, Southeast Asia, and the Middle East. See our product catalog for additional grades of alloy steel seamless pipes.
