Kohlenstoffstahl

Case-hardening is a process applied to low-carbon and, generally, machinable steels to improve their wear resistance and, by leaving a relatively soft core, their toughness and impact resistance, also.

​

Carburising - another name for case-hardening - occurs via a gaseous phase at 825-925℃, usually created when propane or butane is introduced to the heated steel in a sealed furnace and diffuses into the surface to carburize the carbon present in the material's surface. This can then be either quenched or double quenched to increase the depth of carburisation.

​

Case-hardened steels are used to manufacture parts for mechanical engineering purposes, such as gears, cams, valves, timing wheels, pinions, shafts, crankshafts, and con-rods, among others. These are usually supplied in bar form to reflect the fact that they are intended for machining.
