ASME SA213 / ASTM A213 T5 / 1.7362 / X11CrMo5 Alloy Steel Heat Exchanger Tube
 

Chemical Compositions of ASTM A213 / ASME SA213 T5 Alloy Steel Seamless Tube

Mechanical Properties ASTM A213 / ASME SA213 T5 Alloy Steel Seamless Tube

Parent Standard:

• ASTM A213/A213M - Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.

Equivalent Material Specifications:

• ASME SA-213 T5: Identical specification for ASME Boiler and Pressure Vessel Code construction.

• UNS Number: K41545

• European (EN): 12CrMo5 / 1.7362 (similar, not exact).

• German (DIN): 12CrMo195 (similar).

Comparison with Common Grades:

• vs. T11 (1.25Cr-0.5Mo): T5 has higher Cr for better oxidation/corrosion resistance.

• vs. T22 (2.25Cr-1Mo): T5 has higher Cr but lower Mo; T22 generally has better creep strength at very high temperatures.

• vs. T9 (9Cr-1Mo): T9 has significantly higher Cr and Mo, offering superior temperature capability and strength.

Application

• Key Properties for Application:

  • Oxidation Resistance: Good resistance to scaling in steam and flue gas environments.

  • Sulfidation Resistance: Resistant to attack from sulfur compounds in fuel gases/oils, making it suitable for refinery heaters.

  • Strength at Temperature: Maintains useful strength under creep conditions.

• Typical Applications:

  • Superheater and Reheater Tubes in fossil fuel power plants.

  • Heat Exchanger Tubes in petroleum refineries (e.g., catalytic cracking units).

  • Process Heater Tubes in chemical plants.

  • Piping for high-temperature steam or process fluids.
