ASTM A204 Grade B Sheets and Plates are alloy steels that contain molybdenum (0.45–0.65%), enhancing their strength and heat resistance. They also include carbon (0.15–0.23%), manganese (0.90–1.50%), silicon (0.13–0.45%), along with small amounts of phosphorus and sulfur. These plates boast a minimum tensile strength of 515 MPa, a yield strength of 285 MPa, and an elongation of 20%. They are known for their good weldability and formability, while also providing enhanced resistance to creep and oxidation at high temperatures, making them perfect for high-temperature pressure equipment applications.
