What is heat treatment stress

The residual force of heat treatment is the stress of the workpiece after heat treatment, and the shape of the workpiece. Size and performance are extremely important. When it exceeds the yield strength of the material; It causes the distortion of the workpiece, which can cause the workpiece to crack when it exceeds the limit of the strength of the material. This is its harmful side and should be reduced and eliminated.
But under certain conditions, the control of stress can improve the mechanical properties and service life of the parts, which can be beneficial. The distribution and change of stress during heat treatment are analyzed, and the reasonable distribution of steel is of great practical significance to improve the product quality.
