ASTM A213 T11 Alloy Steel Seamless Boiler Tubes For High Temperature Service

Chemical Composition (%) max

Mechanical Properties

ASTM A213 This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc. T11 alloy tubes are widely used in high-temperature applications due to their excellent mechanical properties, oxidation resistance, and creep strength,including power generation, petrochemical, oil and gas, heat treatment, chemical processing, and energy sectors.

Key Advantages

High-Temperature Strength: Maintains mechanical properties at elevated temperatures.

Corrosion Resistance: Suitable for corrosive environments, including those with sulfur and other aggressive elements.

Oxidation Resistance and Creep Resistance: Resists scaling and oxidation in high-temperature environments and withstands long-term exposure to high stress.

Applications

Power Generation Industry --- in boilers, superheaters, and reheaters.

Petrochemical Industry --- in high-temperature pipelines, reactors, and heat exchangers.

Oil and Gas Industry --- in refineries and petrochemical plants for high-temperature piping and heat exchangers.

Heat Treatment Equipment --- Employed in furnaces, annealing lines, and other heat treatment systems.

Chemical Processing Industry --- in reactors, distillation columns, and high-temperature pipelines.

Energy Sector --- in thermal power plants and combined cycle power plants.

Reason: Provides excellent high-temperature strength and oxidation / corrosion resistance, and maintains structural integrity under high temperatures and pressures.
