Case Carburizing Hardening & Temperingis a heat treatment process that enhances the surface hardness of low-carbon steel while maintaining a tough and ductile core. The component is heated in a carbon-rich atmosphere to allow carbon to diffuse into the surface. After sufficient carburization, it is quenched and tempered. This results in a wear-resistant outer layer and a tough interior — ideal for parts subjected to friction and impact. It's widely used in gears, camshafts, and other components where surface durability is crucial.
