Frequently Asked Questions

How precise is the carbon potential control?

Continuous carbon potential measurement and fully automatic control enable very high reproducibility, ideal for series processes with tight tolerances.

Is the furnace ATEX-compliant?

Yes, our carburizing furnaces are supplied with a complete explosion protection system.

What temperature range is used for carburising?

Up to 1000 °C. The carburising process itself typically runs between 850 and 950 °C, depending on the material and the required case depth.

Which atmosphere is used?

N₂/methanol as carrier gas with propane as enrichment gas. The composition is regulated via continuous carbon potential measurement.
