In this process, volume hardening of ferrous materials is obtained by heating metals to high temperature and cooling rapidly. The structure of the materials is changed and improved properties are achieved. The strength of the materials increases significantly. Cooling medium is water, oil, air, depending on the type of steel being treated
The tempering process which is carried out after hardening confers optimum properties on the materials, depending on the customer's requirements or design preferences
EXAMPLE: Automotive components, cement machinery, earth moving equipment, etc
