From a regular reader in the Turkish heat treat market about commercial heat treater “DÖNÜŞÜM ISIL İŞLEM”, one of the larger in the country;

Dönüşüm Isıl İşlem, based in Kocaeli, has one of the most qualified heat treatment facilities in Turkey, which has continued its activities both domestically and internationally since 2010.

Heat treatment is generally performed for tool and die steels, stainless steels, and special metals. In this way, it cooperates directly and indirectly with many sectors such as automotive, aviation, plastic, glass, defense, mining, medical, and energy industries. Also, there is a steel service department called Dönüşüm Metal which supplies tool & mold steel, stainless steel, and special alloys, both department works coordinately. Dönüşüm Metal ve Isıl İşlem is the first company in Turkey to provide steel and heat treatment services together.

The properties of metals and alloys in engineering applications vary depending on the atomic, crystalline, and microstructure of the materials. The microstructure in equilibrium can be predicted by looking at the equilibrium diagrams of metals or alloys. In practical terms, the mechanical properties can be changed as desired by various heat treatments. These heat treatment processes involve raising a metal or alloy to a certain temperature, holding it at that temperature for the required time, and finally cooling it from that temperature. If necessary, this solid-state process can be repeated multiple times. In short, the heat treatment process is the name given to the heating and cooling operations performed to obtain the desired mechanical properties of metals or alloys. The following changes can occur in the properties of metal alloys by heat treatment:

•    Increasing Ductility
•    Internal-Stress Relieving Treatment
•    Grain Size Refining
•    Improving Tensile Strength
•    Improving Toughness
•    Improving Machining
•    Magnetic and Electrical Properties
•    Recrystallisation

The sky is the limit for Dönüşüm Isıl İşlem, as it continues its investments to improve its abilities. In addition, it provides engineering services to its business partners by developing special processes with its experienced and dynamic engineering staff.
