Q:What is tempering?

Tempering refers to a heat treatment process in which quenched metal products or parts are heated to a certain temperature, kept warm for a certain period, and then cooled in a certain way. Tempering is an operation performed immediately after quenching and is usually the last step in the heat treatment of the workpiece. Therefore, people call the combined process of quenching and tempering the final heat treatment.
