Product Description
ASME SA213 T11 Alloy Steel Cold Drawn Seamless Round Tube For Boiler
ASTM A213 T11 tubes are stainless steel tubes specifically designed for high-temperature service applications in heat exchangers, superheaters, and boilers. These tubes feature a composition including carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, and molybdenum, which provides exceptional tensile strength, high yield strength, and superior hardness.
T11 boiler tubes can be manufactured through hot working or cold drawing processes and are available in seamless, ERW (Electric Resistance Welded), welded, or fabricated forms. They offer excellent resistance to high temperatures and corrosion, along with good ductility for machining operations such as flanging and bending. The material's compatibility with fusion welding makes it ideal for power generation and petrochemical industries.

ASME SA213 T5 Seamless Tubes Standard Specification
This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, including Grades T91, TP304, and others. These steels are designed for high-temperature service with enhanced creep-rupture strength.
Key Requirements:
- Grades containing "H" designation provide higher creep-rupture strength
- Standard tubing sizes range from 1/8" [3.2 mm] inside diameter to 5" [127 mm] outside diameter
- Wall thickness ranges from 0.015 to 0.500 in. [0.4 to 12.7 mm]
- Available in both SI units and inch-pound units as separate standards
