These molybdenum-alloyed steels, known as SA 204 Grade A and B, boast impressive strength, excellent weldability, and remarkable resistance to creep and corrosion even in elevated temperatures. Manufactured in accordance with ASTM/ASME standards, these plates find extensive use in thermal power plants, boilers, and refinery equipment. With precise cutting, a superior surface finish, and adherence to international quality standards, Daksh provides reliable steel solutions for industries that demand durable and long-lasting materials.
SA 204 GR A/B Sheets and Plates are low-alloy steels primarily enriched with molybdenum (0.45–0.65%) to enhance their strength at high temperatures and boost corrosion resistance. Grade A features a slightly lower carbon content compared to Grade B, which improves its weldability. The mechanical properties include a tensile strength ranging from 415–585 MPa for Grade A and 485–620 MPa for Grade B, along with commendable yield strength and ductility. These plates are specifically crafted for high-temperature service and demonstrate good notch toughness, making them ideal for welded pressure vessels and components that face thermal stress and corrosive environments.
