Hassan Sheets and Plate Manufacturer and Supplier, based in Riyadh, Saudi Arabia, stands out as a top provider of high-quality steel products specifically designed for pressure vessel and heat-resistant applications. Among their specialized products are the SA 204 Grade A and B Sheets and Plates, which are celebrated for their outstanding performance in high-temperature environments. These molybdenum-alloyed plates boast enhanced strength, corrosion resistance, and excellent weldability, making them perfect for boilers, pressure vessels, and various industrial equipment. Hassan is committed to adhering to ASTM standards, delivering precision-engineered materials that meet the rigorous demands of industries like petrochemicals, power generation, and oil refining throughout the Middle East.
SA 204 Grade A/B Sheets and Plates are crafted from molybdenum-alloyed carbon steel, specifically designed for high-temperature pressure vessel applications. Their composition features carbon (max 0.27%), manganese (0.90–1.50%), phosphorus (max 0.035%), sulfur (max 0.035%), and molybdenum (0.45–0.65%). These grades provide impressive mechanical strength and thermal stability. Grade A has a minimum yield strength of 220 MPa, while Grade B offers around 275 MPa. Both grades demonstrate tensile strength between 415 and 585 MPa, along with good ductility and weldability. They are typically supplied in either the as-rolled or normalized condition to enhance their structural integrity under thermal stress.
