The production of Quenched and Tempered Carbon Steel Sheet and Plate involves a carefully controlled heat treatment process. This includes heating the steel to a high temperature (quenching) and then cooling and reheating it in a controlled manner (tempering). This process enhances the mechanical properties by refining the grain structure. Typically, the composition includes carbon (0.15%–0.40%), along with manganese, chromium, molybdenum, and nickel, depending on the specific grade. Q&T plates are known for their high tensile strength (up to 1800 MPa), improved yield strength, and outstanding toughness and ductility. These features make Q&T steels ideal for structural components that face high loads, abrasion, and impact.
