The role of heat treatment in railway emergency clamping device

Increase strength and hardness

By quenching and tempering treatment, the strength and hardness of the railway emergency clamping device can be improved, so that it can withstand greater load and impact force.

Improve wear resistance

The surface quenching treatment can significantly improve the surface wear resistance of the railway emergency clamping device and prolong the service life.

Stress relief

The tempering treatment can eliminate the stress generated during the quenching process and prevent the device from cracking or deformation due to stress concentration during use.
