ASTM A213 T11 Seamless Alloy Steel Low Fin Tubes For Thermal Power Plants
ASTM A213 T11 is a seamless ferritic alloy boiler, superheater, and heat exchanger tube with a nominal composition of 1.25Cr-0.5Mo alloy steel. It is the standard base material for integrally extruded/hot-rolled low-finned tubes, with fins integrally formed from the outer wall of the T11 seamless tube. Its performance is superior to carbon steel materials A179 and A192.
Advantages:
T11 alloy tubes maintain high creep rupture strength under continuous operating conditions up to 540℃, and exhibits excellent resistance to oxidation from flue gas and process exhaust gases, as well as mild sulfidation corrosion. It also demonstrates stable thermal fatigue resistance under frequent thermal cycling conditions, possesses excellent plasticity, and is suitable for finned rolling.

| T11 | 60ksi (415 MPa) | 30ksi (205 MPa) | 30% |
Application ( Not limited to the following )
ASTM A213 T11 is a seamless ferritic alloy steel with stable creep strength, resistance to steam/flue gas oxidation, and good weldability, suitable for long-term use at ≤540℃.
Thermal Power Plants:Boiler Economizers & Flue Gas Waste Heat Recovery Heat Exchangers
*T11 can withstand the oxidation of medium and high temperature flue gas and sulfur flue gas, as well as thermal cycling fatigue, which is far superior to carbon steel A179/A192.
Gas Turbine Waste Heat Boilers (HRSG)
*The convection section of the waste heat recovery steam generator uses low-finned T11 tubes to recover high-temperature waste heat from exhaust gas to generate steam.
Petrochemical & Oil Refining Industry:Refinery High‑Temperature Process Heaters & Convection Sections
Furnace Air Preheaters
*The combustion air is preheated using high-temperature furnace flue gas; the low-fin T11 tube can resist the erosion and oxidation of high-temperature flue gas.
Metallurgical and Waste Heat Recovery Projects
*Industrial Kiln Flue Gas Waste Heat Recovery System: Low-finned T11 tubes recover waste heat for preheating boiler feedwater or process air; a core energy-saving component.
