Gas Nitriding
With gas nitriding, the edge of a workpiece is either finished with nitrogen or with nitrogen and carbon (gas nitrocarburising) in a gaseous atmosphere. To improve the tribological characteristics of the component, it can then be oxidised.
Advantages
- Improves resistance to wear and tear
- Increases tensile strength
- Increased compression strength
- Improved sliding properties
Materials
- Non- and low-alloy steels
- Case-hardening steels
- Tool steels
- Nitriding steels
Available plant sizes
- Length 5000 mm, diameter 980 mm
