ASTM A213 T5 (UNS K41545) Alloy Steel Seamless Tube For Boiler and Superheater
ASTM A213 T5 Alloy Steel Seamless Tube (UNS K41545) is a high-performance tubular product specifically engineered for high-temperature and high-pressure applications, widely used in boilers, superheaters, and heat exchanger systems. Manufactured from chromium-molybdenum alloy steel (5Cr-0.5Mo), it exhibits exceptional creep resistance, oxidation resistance, and elevated-temperature strength, ensuring structural stability under prolonged thermal stress. The seamless construction enhances pressure-bearing capacity and reliability, complying with ASTM A213 international standards, making it ideal for demanding industrial environments such as power generation and petrochemical sectors.

2. Key Adventages
Suitable for high-temperature service up to 600°C (1112°F) with excellent creep resistance and long-term strength.
4-6% Chromium (Cr) content provides strong resistance to steam oxidation and high-temperature corrosion.
Tensile strength ≥415 MPa, yield strength ≥205 MPa, and elongation ≥30% ensure high reliability and durability.
Seamless construction ensures superior pressure-bearing capacity and safety in demanding applications.
Low carbon content (≤0.15%) ensures good weldability and machinability, with recommended pre/post-weld heat treatment.
3. Key Applications
Boiler tubes: For evaporators, superheaters, and reheaters in high-pressure power plant boilers
Steam pipelines: Critical pipelines for high-temperature/pressure steam transmission
Refining units: Heating tubes for catalytic crackers and hydroprocessing units
Cracking furnace tubes: High-temperature reaction pipes in ethylene crackers
Heat exchangers: Core components for shell-and-tube heat exchangers
Reactor piping: High-pressure reaction pipes in fertilizer/ammonia production
