What is the Carbonitration?
Carbonitration, a thermochemical process, aims to improve the mechanical properties of parts by enriching the surface layer with carbon. This process is typically carried out using continuous furnaces.
The carbonitration process consists of three steps. In the first step, the parts are subjected to a carbon-rich environment at temperatures ranging from 750 to 900 °C for a specified time in a process called annealing. The second step, known as quenching, involves exposing the parts to the target temperature for a certain period and then rapidly cooling them in oil to create a martensitic phase. The third step, tempering, aims to reduce internal stresses in the material’s structure.
Carbonitration is used when low-carbon steels require a surface layer with high hardness and resistance to wear. This process is commonly preferred for fasteners, automotive, and other parts in various industries.

As Termosan Heat Treatment Industry and Trade Inc., we offer our customers high-quality heat treatment solutions. We enhance the durability of your parts through specialized processes like carburizing.
Carburizing is a heat treatment method applied to improve the surface properties of metal parts and make them more resistant to wear. This process involves diffusing carbon and nitrogen elements into the surface of the parts through diffusion. As a result, the surface hardness of the parts increases, and their resistance to wear and fatigue improves.
With ISO 9001 and IATF 16949 certifications, we continuously enhance our technological infrastructure to provide solutions that meet your company’s specific needs and comply with the latest industry standards.
