Alloy Steel Seamless Tubes Chromium-Molybdenum Alloy Steel A213 T5
Seamless Boiler Tube
SA213 T5 is a specification for seamless ferritic and austenitic
alloy-steel boiler, superheater, and heat-exchanger tubes under the
ASME SA213/ASTM A213 standard. The T5 grade is a
chromium-molybdenum alloy steel designed for high-temperature
service, particularly in boilers, superheaters, and heat
exchangers. It offers good oxidation resistance and
high-temperature strength, making it suitable for
elevated-temperature applications.
ASTM A213 Standard
Key Features of SA213 T5:
Material Type: Chromium-molybdenum alloy steel.
High-Temperature Performance: Designed for use in high-temperature environments, such as boilers and superheaters.
Corrosion Resistance: Good resistance to oxidation and scaling at elevated temperatures.
Weldability: Can be welded using appropriate procedures, but preheating and post-weld heat treatment may be required.
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.
