Harder, more precise and less corrosion.
In our vacuum furnaces we harden work pieces that require a very precise temperature.
Distortion-sensitive precision components, mould components and tools are hardened here in a low-pressure range between 10-3 mbar and quenched in a nitrogen gas flow.
Hardening of low-alloy steel is no problem with this process.
We have brought vacuum hardening to perfection in the past few years: It is environmentally friendly, clean and economical due to modern program controls that ensure complete reproducibility. The treated work piece retains a metallic bright surface in any case.
With regard to dimensional change and distortion, there is no comparable process.
