Hardening is the heating and subsequent cooling of steel at such a speed that there is a considerable increase in hardness, either on the surface or throughout. In most cases hardening takes place in conjunction with subsequent reheating, the annealing.
Read more →Case hardening is a thermo-chemical process. Within the framework of this process, the surface layer of components is enriched with carbon (carburisation) or carbon and nitrogen (carbonitriding), in order to improve the mechanical properties of the component surface layer. For both process variants, various plant technologies, such as chamber furnaces, through-type furnaces, salt baths, low pressure systems etc., are available.
