A selection of processes is listed below.

Thermal Processes

Technology

Hardening

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.

Thermochemical Processes

Technology

Case Hardening

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.

Nitriding (NITAI®)

All the nitriding and nitrocarburising processes of the HAUCK Group share the designation NITAI® . Nitriding and nitrocarburising improve the mechanical properties of component surface layers.

Phosphating

Phosphating is a chemical/electro-chemical process in which thin, fine-crystalline and water insoluble phosphates are generated on metal surfaces from phosphoric acid solutions in a dipping or spraying procedure.
