Alloy Steel Tubes are high-strength tubular products designed for high-temperature, high-pressure, and severe service conditions. These tubes are alloyed with elements such as chromium, molybdenum, and manganese to enhance mechanical strength, creep resistance, oxidation resistance, and long-term reliability.
Alloy Steel Tubes are manufactured in seamless and welded forms and are widely used in boilers, superheaters, heat exchangers, power plants, refineries, and industrial process systems where consistent performance and durability are critical.
Alloy Steel Tubes are produced in accordance with ASTM and ASME standards for pressure and temperature service. Common specifications include ASTM A179, ASTM A192, ASTM A210, ASTM A213, and ASME SA213, covering low alloy and chromium-molybdenum tube grades suitable for boiler, heat exchanger, and high-temperature applications.
