Buy ASTM A213 T23 (UNS K41650) seamless ferritic alloy steel tubes for high-temperature boilers, heaters & superheaters and oxidation resist
ASTM A213 / ASME SA213 T23 Seamless Alloy Steel Tubes are high-performance ferritic alloy steel tubes engineered for demanding high-temperature and high-pressure applications, especially in modern boiler, superheater, reheater, and heat-exchanger systems. These tubes are manufactured to the ASTM A213 / ASME SA213 standard and are widely used in thermal power plants, refineries, petrochemical units, and industrial heating equipment.
Grade T23 (UNS K41650) is an improved 2.25Cr–1W alloy steel that offers higher creep strength, superior oxidation resistance, enhanced weldability, and better thermal stability compared with earlier grades like T22 — making it ideal for advanced ultra-supercritical boilers and high-temperature pressure environments.
