Vacuum Treatment

The Haupt – Vacuum Treatments

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.
