Heat treatment is an industrial process that is used for changing the physical and at times the chemical properties of a material. In the manufacturing segment, this process is commonly used in order to change metallurgical properties. The metal is heated in a furnace up to 2,000-2,700°C, which results in the absence of air as well as other gases, so that contamination does not takes place. Various industries such as automotive, aerospace and general machinery make use of this process to develop high precision products.
