ASTM A213 T22 tubes are chromium-molybdenum alloy steel tubes widely used in applications that require high temperature and high pressure resistance. These tubes are manufactured as per ASTM A213 / ASME SA213 specifications and are primarily intended for boilers, superheaters, reheaters, and heat exchanger services. The presence of chromium and molybdenum enhances the tube’s strength, oxidation resistance, and creep resistance, making it suitable for severe operating environments.
The chemical composition of ASTM A213 T22 tubes typically includes 2.0–2.5% chromium and 0.87–1.13% molybdenum, along with controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur. This alloy combination provides excellent resistance to corrosion and scaling at elevated temperatures, while also improving weldability and long-term performance. These properties make T22 tubes a preferred choice over standard carbon steel tubes in critical applications..
From a mechanical standpoint, ASTM A213 T22 tubes exhibit good tensile strength, yield strength, and elongation, allowing them to withstand thermal stress and pressure fluctuations without deformation or failure. They are designed to perform reliably under continuous high-temperature exposure, which is essential in power plants and process industries where downtime can be costly..
ASTM A213 T22 tubes are available in seamless form and are supplied in a wide range of outer diameters, wall thicknesses, and schedules. Common sizes range from small-diameter boiler tubes to larger heat exchanger tubes, with customization available as per project requirements. End finishes may include plain ends, beveled ends, or threaded ends, depending on application needs..

ASTM A213 T22 Tubes are primarily used in high temperature and high pressure applications such as boilers, superheaters, reheaters, and heat exchangers. They are widely used in power plants, petrochemical plants, refineries, and chemical processing industries due to their excellent strength and heat resistance.
The designation “T22” refers to a chromium-molybdenum alloy steel grade containing approximately 2.25% chromium and 1% molybdenum. This composition provides enhanced creep resistance, oxidation resistance, and strength at elevated temperatures.
ASTM A213 T22 Tubes are primarily manufactured in seamless form to ensure superior strength and reliability under high pressure and temperature conditions. Seamless construction minimizes the risk of weld-related failures in critical applications.
ASTM A213 T22 Tubes are supplied in heat-treated conditions such as annealed, normalized, or normalized and tempered. Heat treatment improves mechanical properties and ensures consistent performance in high-temperature service.
