A516 Gr.55 Steel Plate for Boiler and Pressure Vessel

A516 Gr.55 steel is an American standard pressure vessel steel plate, classified as an alloy steel, complying with the ASTM A516 standard. A516 Grade 55 pressure vessel steel plate exhibits excellent wear resistance and corrosion resistance, making it widely used in the fabrication of various engineering structural components. A516 Gr.55 boiler steel plates are primarily utilized in industries such as petroleum, chemical, power plants, and boilers for manufacturing equipment and components like reactors, heat exchangers, separators, spherical tanks, gas storage tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes for hydroelectric power stations, and turbine volutes.

The chemical composition of A516Gr.55 boiler steel plates mainly includes elements such as iron, carbon, and manganese, with their content influencing the mechanical properties and corrosion resistance of the material. A516 Grade 55 pressure vessel steel is a fully killed steel, with a thickness range of 6–305 mm. A516Gr55 steel plates with a thickness of ≤40 mm are typically supplied in the as-rolled condition, while those with a thickness greater than 40 mm require normalizing treatment.
