• Traditional case-hardening process in which carbon is dissolved in the surface layer of a low-carbon steel at a temperature sufficient to render the steel austenitic, followed by quenching and tempering to form martensitic microstructure.
• Carbonitriding hardens surface of steel by diffusing carbon and nitrogen simultaneously into steel in carburizing atmosphere with ammonia gas at around 850��C lower than typical carburizing temperature.
• It offers several advantages over carburizing, including low distortion, bigger resistance to softening during tempering and fatigue strength.
