What are ASTM A213 T22 alloy steel seamless tubes?

ASTM A213 T22 alloy steel seamless tubes are a critical component in applications involving elevated temperatures and pressures. This specification covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. The T22 grade, a chrome moly alloy, is specifically designed for its excellent strength, resistance to creep, and corrosion resistance at high temperatures. It is often referred to by its ASME equivalent, ASME SA213 T22. The UNS K21590 T22 designation also identifies this versatile alloy, widely used as T22 boiler tubes and SA213 heater tubes in demanding industrial settings.
