Main board

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.

CHARACTERISTICS

  • 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

DEPTH

From 0.05 to 0.30 mm

APPEARANCE
