Numerous industrial applications require a hard wear-resistant surface called the case, and a relatively soft, tough core. This is achieved by case hardening. Information above various case hardening methods is given in this article. The first three methods change the chemical composition, carburizing by the addition of carbon, nitriding by the addition of nitrogen and cyanidingcarbonitriding by the addition of both carbon and nitrogen. The last two methods do not change the chemical composition of the steel and are essentially shallow-hardening methods. In flame and induction hardening the steel must be capable of being hardened and therefore, the carbon content must be about 0.30 percent or higher.
