After the heating phase, the item must be cooled. Just like the correct setting of the temperature, this cooling phase is also very important as it depends on the technique applied (that is, relative to the type of steel utilised) and may be effectuated more or less drastically. In this phase, the tempering process is concluded upon obtaining the transformation of the structure. Cooling can be carried out with water, oil, a mixture of cooling oils and water, still air or forced air. Each of these aforementioned methods will ensure the specific mechanical characteristics of the item.
