ASTM A213 Grade T22 Alloy Steel Tube supplied by Hebei K-Steel Pipe Indsutry

 ASTM A213 Grade T22 alloy steel tube is a high-performance chromium-molybdenum (2.25Cr–1Mo) steel tube designed for high-temperature and high-pressure service. It is widely used in power generation, petrochemical, and industrial boilers, where durability, creep resistance, and oxidation resistance are critical.

T22 offers a perfect balance of strength, thermal stability, and long-term service performance, making it suitable for superheaters, heat exchangers, and high-temperature piping systems. The Hebei K-Steel Pipe Industry seamless manufacturing process ensures a uniform microstructure, high integrity, and reliable mechanical properties.

Key Features:

1) Excellent high-temperature strength and creep resistance

2) Good resistance to high-temperature oxidation and hydrogen attack

3) Reliable performance under cyclic thermal loading

4) Good weldability with proper preheating and post-weld heat treatment (PWHT)
