ASTM A213 T23 is a chromium-molybdenum alloy steel grade engineered to deliver improved creep strength, oxidation resistance, and long-term thermal stability compared to conventional grades such as T22. A213 T23 tubes are extensively used in power plants, thermal stations, petrochemical refineries, and high-pressure piping systems where material integrity under continuous heat exposure is critical.
As a leading SA213 T23 Tubes stockist, we supply ASME SA213 Grade T23 Seamless Tubes manufactured in India. Our ASTM A213 T23 Tubes are part of our comprehensive range of alloy steel seamless boiler tubes designed for high-temperature and high-pressure applications in boilers, superheaters, reheaters, and heat exchangers.
These ASTM A213 T23 Tubes are manufactured in accordance with ASTM A213 / ASME SA213 specifications for seamless ferritic alloy steel tubing. We supply ASTM A213 T23 seamless tubes in various sizes, wall thicknesses, and heat treatment conditions with full traceability, mill test certificates, and third-party inspection documentation.
What Are ASTM A213 T23 Tubes?
ASTM A213 T23 Tubes are seamless ferritic alloy steel tubes developed for high-temperature service in power generation, petrochemical, and industrial boiler applications. These tubes belong to the chromium-molybdenum (chrome-moly) family and offer improved creep strength, oxidation resistance, and thermal stability.
While ASTM A213 T22 remains a reliable option for many boiler and superheater systems, T23 alloy steel tubes provide enhanced performance under more demanding operating conditions. Both grades comply with ASME SA213 standards and are widely used in heat exchangers, steam pipelines, and pressure vessels.
Manufactured from UNS K41650 alloy, T23 tubes are an evolution of T22 chrome moly tubes, with additional alloying elements—vanadium, niobium, and tungsten—to improve high-temperature strength. T23 tubes are ideal for ultra-supercritical applications requiring extended service life and resistance to creep deformation.

Chemical Composition of ASTM A213 T23 Alloy Steel Tubes
The performance and reliability of ASTM A213 T22 Tubes are rooted in their carefully balanced chemical composition. These T22 chrome moly tubes, made from UNS K21590 T22 alloy, are specifically engineered to withstand high-temperature and high-pressure environments—making them ideal for use in T22 boiler tubes, SA213 T22 heater tubes, and other thermal systems.
At USA Piping Solution, we manufacture and supply ASTM A213 Gr T22 tubes in full compliance with ASTM A213 and ASME SA213 T22 specifications. Each batch is tested for chemical accuracy to ensure consistency, corrosion resistance, and long-term service in critical applications.
