ASTM A213 T5 Tubes Manufacturer & Supplier

ASTM A213 T5 is a high-chromium seamless alloy tube engineered for boilers and heat exchangers. It provides exceptional corrosion and heat resistance. All our ASTM A213 T5 seamless tubes conform to ASTM A213 / ASME SA-213 and general requirements per ASTM A1016 / ASME SA-1016. The chromium concentration of 4.00–6.00% ensures robust oxidation resistance, whilst 0.45–0.65% molybdenum enhances creep strength under extended heat conditions. This material delivers the durability required for high-temperature, critical-path industrial piping applications.

T5 Alloy Steel Seamless Tubes have a minimum yield strength of 205 MPa (30 ksi) and a minimum tensile strength of 415 MPa (60 ksi). They have a maximum hardness of 163 HB and a maximum elongation of 30%. This combination of mechanical properties renders them well-suited for components that operate at temperatures of up to approximately 600°C (1100°F) and contain pressure.

ASTM A213 T5 Tube Industrial Applications

ASTM A213 T5 alloy steel tubes are designed for high-temperature and high-pressure applications. Boiler tubes, superheater tubes, heat-exchanger tubes and furnace components are frequently employed in refinery, petrochemical and power generation operations.

Power Generation

Used in superheaters and reheaters for power plants, maintaining structural strength during intense heat and suitable for elevated temperature service; allowable limits depend on the design code.

Oil and Gas and Petrochemical

Ideal for furnace coils and heat exchangers, as the chromium resists corrosion from high-sulphur crude oil at extreme processing temperatures.

Chemical Processing and Refineries

Used in reactors and furnace sections, it provides important oxidation resistance for long-term use in harsh, high-temperature chemical conditions.
