A204 Gr. B Pressure Vessel Alloy Plates
ASTM A204 Grade B is a boiler quality grade of steel. Astm A204 Grade B boiler Steel Plates are designed with premium ingredients of carbon, molybdenum, manganese sulfur, phosphorus, and silicon. The components embedded in these plates give them enhanced resistance to corrosion and reducing media. ASTM A204 alloy steel plates work well in high pressure and high temperature applications.
Sa204 Gr. B vessel plates have excellent mechanical properties. These plates have a tensile strength between 440 and 590 MPa and a yield strength between 220 and 275 MPa. They can be elongated by at least 19% in the system.
A204 Grade B vessel steel plates are commonly used in industrial boilers, pressure vessel heat sinks, ship hulls, submarines, aerospace, and other applications. All of our products can be customized to specific customer requirements.
