What are the heat treatment methods for coupling components?

When heat treat the coupling, certain requirements need to be met.

1. Couplings can undergo heat treatment process after forging, and it should be preheated before heat treatment, which can improve the organizational performance and increase the machinability.

2. When conducting heat treatment, it is necessary to process according to the provided drawings, as well as undergo quenching and tempering processing. If the cutting amount on the surface exceeds five millimeters, stress relief treatment is also required.

3. When performing stress relief treatment, the temperature is carried out should be about thirty degrees Celsius lower than the temperature at which the tempering is carried out, and mechanical performance testing should be conducted after the stress relief treatment is completed.

Each heat treatment method is not carried out casually, and strict adherence to requirements is required to achieve the desired effect.
