Alloy grade T11 steel offers high oxidation resistance, plasticity and thermal strength even at up 580℃. It has good weldability, needs preheating to 300℃ before welding and removing stress treatment after welding, has been widely used in high pressure, ultra-high pressure, subcritical power station boiler superheater, header and main steam duct. WIHO metals is a leading alloy steel tube supplier and manufacturer, we supply alloy steel ASTM A213 Grade T11 Seamless steel tubes manufactured in hot finished or cold finished and equivalent material for boiler and economizer, heater, superheater and reheater system in various sizes and specifications.

Grade T11 and P11 tubing

Grade T11 and P11 seamless steel pipes are included in ASTM or ASME suited for boiler superheater, reheater pipe and heat-exchanger tubes. Grade T11 specified in ASTM A213 covers seamless Ferritic and Austenitic steel tube, and ASTM A335 Grade P11 Seamless Ferritic Alloy-Steel Pipe and are used mainly for High-Temperature Services such as boiler, superheater, and heat exchanger. We can say that Gr T11 and P11 have been substituted for another one when the same purpose.
