Heat & surface treatment

Case hardening is one of the thermochemical processes. In this process, the surface layer of components and tools is carburized with a carbon-emitting medium and then quenched, improving the mechanical properties (e.g. wear) of the component's surface layer.

Carburization is usually at temperatures of 880 to 950° C. After the hardening of the carburized parts, Tempering is generally required to reduce the stresses resulting from hardening and to achieve the required strength.

A range of different systems such as chamber furnaces and continuous furnaces are available for case hardening. Oils are generally the media used for quenching.

• High surface hardness
• Good wear resistance
• Good shock resistance
