Gas nitriding

Gas nitriding is a process of nitrogen diffusion in the material at temperature between 450-580°C, in ammonia and nitrogen base atmosphere. The result in nitrogen is a function related to temperature and ammonia dissociation rate. The result is a layer of nitrogen diffusion in steel (0.2-0.6 mm) which has high hardness and wear resistance. Nitriding is used for alloyed and stainless steels.

The furnaces used for this process are:
