What is hardening?

Metallic materials are preferred for their low hardness so that they can be processed more easily. The process made to give the parts mechanical properties and make them suitable for use is called the hardening process. In the hardening process, the material is heated to 820-900ºC temperatures. Then, sudden cooling and then tempering processes are done. The tempering process takes place at a lower temperature (200ºC to 650ºC) It is a heat treatment applied to improve the properties of the parts by eliminating the tension and fragile structure formed during the hardening process.
