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
