ISO Certified Manufacturer
ASME SA213 T22 is a seamless ferritic alloy steel tube specified for boiler, superheater, and heat exchanger service under ASME SA213 / ASTM A213 standard. The T22 grade contains 2.00–2.50% chromium and 0.87–1.13% molybdenum (2.25Cr-1Mo), offering superior creep resistance and hydrogen embrittlement resistance at elevated temperatures up to 620°C.
SA213 T22 alloy steel tubes are used in high-pressure steam superheaters, reheaters, high-temperature heat exchangers, and reformer tubing in petrochemical plants, refineries, and power generation facilities. They are suitable for service in hydrogen-rich environments and under high-temperature sulfidation conditions where P11 grade is insufficient.
Spark Steel supplies ASME SA213 T22 seamless alloy steel tubes with tensile strength minimum 415 MPa and yield strength minimum 205 MPa. Available in tube OD from 12.7 mm to 76.2 mm with wall thicknesses per BWG or custom dimensions. Supplied in annealed or normalized and tempered condition with hydrostatic pressure testing and full certification per ASME / ASTM requirements.
