Tempering principle: Tempering is hardened after the workpiece is heated to AC1 below a certain temperature, heat for a certain time, and then cooled to room temperature heat treatment process.

Tempering is followed by quenching, and its purpose is:

1. To eliminate the residual stress generated when quenching the workpiece to prevent deformation and cracking;

2. Adjust the hardness, strength, plasticity and toughness of the workpiece to meet the performance requirements;

3. Stable organization and size, to ensure accuracy;

4. Improve and improve processing performance.

Therefore, tempering is the last important process for the workpiece to achieve the desired performance.

According to the tempering temperature range: tempering can be divided into low temperature tempering, middle temperature tempering and high temperature tempering.

Remarks during use and handling：

During transportation, handle softly and carefully, avoid bumping and damaging the outer packing materials. Moisture and rain prohibited. Steel wire ropes must be stored in dry and well ventilated indoors.
