**Quenched and tempered steel** is created through a two-step heat treatment process: first, the steel is rapidly cooled (quenched) from a high temperature to harden it, and then it’s reheated to a lower temperature (tempered) to lessen brittleness while keeping its strength intact. This method significantly improves mechanical properties like tensile strength, hardness, and impact resistance. Depending on the grade and application, Q&T plates can achieve yield strengths ranging from 500 MPa to over 1100 MPa. Common grades include the 400, 500, and 700 series structural steels.
