Alloy Steel Seamless Bolier Tube A213 T5 High Temperature Superheater Grade

Alloy Steel Seamless Bolier Tube A213 T5 High Temperature Superheater Grade

A213 T5 tube is a specific type of seamless alloy steel tube manufactured according to the ASTM A213 standard, designed for high-temperature service in boilers, superheaters, and heat exchangers

T5 Alloy Steel

• T5 is a type of alloy steel, often referred to as 5% chromium steel. The general composition of T5 steel is:
  • Chromium (Cr): 4.5-5.5%
  • Molybdenum (Mo): 0.44-0.65%
  • Carbon (C): 0.45% maximum
  • Other elements may include silicon, manganese, and traces of sulfur and phosphorus.

Comparison with Other Grades:
SA213 T11: Similar to T5 but with slightly higher chromium content (1.00-1.50%) and lower molybdenum content (0.44-0.65%).
SA213 T22: Higher chromium (1.90-2.60%) and molybdenum (0.87-1.13%) content, offering better high-temperature strength and corrosion resistance.
SA213 T9: Higher chromium (8.00-10.00%) and molybdenum (0.90-1.10%) content, suitable for even more demanding high-temperature applications.
Standards and Certifications:
ASME SA213: Standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes.
ASTM A213: Equivalent to ASME SA213, used for the same applications.
