Q&T In order to increase hardenability, carbon steel plates usually contain manganese, carbon (up to 0.30–0.50%), and additional alloying elements like chromium, molybdenum, or boron. These plates have outstanding impact toughness, yield strength between 600 and 1100 MPa, and high tensile strength (up to 1300 MPa) following quenching and tempering. The procedure preserves weldability while improving ductility, hardness, and grain structure refinement. These plates are designed for demanding structural applications where toughness and strength must be maximised without sacrificing control over crack propagation or fatigue resistance.
