Working principle of tempering

Tempering is the heat treatment process that the workpiece is hardened to a certain temperature below AC1, and then it is cooled for a certain time and then cooled to room temperature. Tempering is usually followed by quenching:

(a) eliminate residual stress during quenching, prevent deformation and cracking; (b) adjust the hardness, strength, plasticity and toughness of the workpiece, and meet the performance requirements;

(c) stable organization and size to ensure accuracy;

(d) improve and improve processability.

Therefore, tempering is the last important process for obtaining the required properties of the workpiece. According to tempering temperature range, tempering can be divided into low temperature tempering, medium temperature tempering and high temperature tempering.
