ASTM A204 Grade B is a boiler quality grade of steel. The Astm A204 Grade B Plate is designed with a superior composition of carbon, molybdenum, manganese sulfur, phosphorus, and silicon. The content embedded in these plates gives them enhanced resistance to corrosive and reducing media. ASTM A204 Alloy Steel Plate works well in high pressure and temperature applications. These plates are designed in thickness between 5mm up to 150mm with widths of 6000mm to 12000mm. Molybednum Steel Plates ASTM A204 Grb have enhanced resistance to acidic media and corrosive constituents. These plates also showcase superior tolerance to crevice corrosion and pitting by acids.

The pressurized vessel ASME Sa204 Gr. b Steel Plate has widths between 1500mm to 2500mm. The versatile plates have superior strength and load-bearing capacity in the system. The ASME Sa204 Gr. b Plate is designed with superior mechanical properties. These plates have a tensile strength between 440 to 590mpa with yield strength between 220 to 275mpa. They can be elongated by a minimum of 19% in the system.

The Astm A204 Gr.B Low Alloy Plate is able to withstand higher levels of pressure and temperatures. These plates showcase excellent creep strength and have low levels of temperature ductility within the system. The A204 Grade B Plate has a solid rock-like body that gives good efficiency in different industries. These plates come along with a flawless finish and have a longer life span. A204 Grade B Steel Plate is commonly seen in industrial boilers, pressure vessels heat dissipation units, ship hulls, submarines, aerospace, and other applications. All our products can be customized as per specific customer requirements.
