If you need case hardening for plain carbon or low alloy steels that typically don’t do well with carburizing, carbonitriding is your heat treating solution. Carbonitriding is a case hardening process yielding thin, hard casings for metal parts or components. It is an altered form of gas carburizing for when you need dimensional control and wear resistance. The change comes from adding ammonia to the concentrated air allowing for carbon and nitrogen to infuse into the surface of the component.

Another significant difference in using Carbonitriding as a heat treatment solution is the lower temperature and short cycle times necessary to complete the process. The casings have shallower depths in a typical range between 0.002” and 0.030.” Adding nitrogen to the equation increases the hardening potential of the newly formed casing.

Following the Carbonitriding process comes the quenching. Quenching of a material takes place in water, brine, oil, or another substance to rapidly cool it. Once complete, the product is then tempered to an individualized level preselected by the customer. This tempering process improves the ductility and toughness of the unit.
