This is a thermochemical treatment through which the superficial layer of a steel is enriched of nitrogen and carbon. Such process creates and an enforced layer that increases the hardness of the superficial layer: after the process of surface enrichment we will move onto a controlled and induces oxidation of the artefact, in an oven set under specific temperatures. This process is facilitated by the action of specific gases that generate an oxide veil of a few microns thickness giving it a typical black colouring.
- Increase of superficial hardness;
- Improved resistance to wear and tear;
- Improved resistance to stress;
- Less Friction;
- 96 hours resistance in salt fogs according to UNI norms.
From 0.05 to 0.30 mm
The product appears neat and in a shade of homogeneous black.
