This thermochemical process is designed to enrich the workpiece with carbon. The method applied at Härterei Reese is based on gas carburisation, which can be very easily regulated and allows precise specifications for subsequent hardening profiles. After carburisation, the components are hardened and then stress relieved in a tempering process. Besides their high surface hardnesses (up to 850 HV) and resistance to wear, the heat treated workpieces also exhibit high fatigue strengths.
Specific time and temperature variations during the carburising, hardening, and stress relief processes serve to optimise the material properties and minimise changes to geometry caused by these processes' special batching techniques.
HÄRTEREI REESE operates highly automated universal chamber and shaft furnaces for case hardening, carbonitriding, and tempering components. Loaded and unloaded automatically, our universal chamber furnaces are suitable for the large scale production of series parts. All important process parameters can then be regulated and documented to precision.
With a maximum utilisable capacity of D 5000 x 5000 mm, our shaft furnaces are designed for large quantities and parts up to 50 t.
In cooperation with major European gear manufacturers, we can supply prefabricated and case hardened gear components in addition to complete gear assemblies. We offer these services to our customers worldwide. If requested, the workpieces need only be finished at their plant. This procedure is highly efficient and cost effective.
