When it comes to composition, ASTM A204 Grade B Sheets and Plates are primarily made from molybdenum alloyed steel, which boosts their strength and ability to handle elevated temperatures. The typical chemical makeup includes carbon (max 0.15%), manganese (0.44–0.94%), silicon (0.13–0.45%), phosphorus (max 0.025%), sulfur (max 0.025%), and molybdenum (0.45–0.65%). On the mechanical side, they deliver a tensile strength ranging from 485 to 620 MPa and a yield strength of at least 275 MPa. With excellent ductility and toughness, these plates are reliable in pressure-containing applications where resistance to creep and thermal fatigue is essential.
