Case hardening aims to improve material's features:
In case hardening, steels with low carbon are used, which get a higher carbon content through carburization of their near-surface layer. During the subsequently sweeping hardening the highest possible martensite is developed in the edge of the workpiece. In the core, by contrast, the yield strength is increased by hardening. Due to its low carbon content, the core of the component retains enough ductility even if it is converted to martensite.
Instead carburization, carbonitration can be used as well.This procedure allows the case hardening of unalloyed materials.
