Description
Structural Steel Boiler Plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheaters, main steam pipes, and heating surfaces of boiler fire chambers. Commonly used boiler steels are low-carbon killed steel smelted in an open hearth furnace or low-carbon steel smelted in an electric furnace, with carbon content ranging from 0.16% to 0.26%. This material is widely used in the petroleum, chemical industry, power plant, boiler, and other industries. You can use it to make reactors, heat exchangers, separators, oil and gas tanks, nuclear reactor pressure shells, boiler drums, high-pressure water pipes of hydropower stations, water turbine shells, and other equipment and components.
Due to its special use, Structural Steel Boiler Plate has the characteristics of withstanding certain pressure, temperature, and medium. At the same time, the material has high strength, strong heat resistance, and is easy to weld. Good weldability can ensure the surface quality of products and avoid leakage. Our products have a variety of varieties and specifications, which can be delivered under heat treatment conditions and meet the requirements of ultrasonic testing. If you have any needs, please contact us.
