These ASTM A204 Grade B Sheets and Plates are primarily made from molybdenum alloyed steel, with carefully controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur. This specific composition boosts the material’s strength, toughness, and ability to withstand high temperatures and pressure. The plates showcase a tensile strength ranging from 415 to 585 MPa and a yield strength of about 240 MPa. They also offer excellent weldability and impact resistance, ensuring they maintain their structural integrity even in high-temperature environments, which makes them ideal for pressure vessels and boiler fabrication.
