PVD, HSN2 coating based on multiple layers doped with Si

HSN2 is a PVD coating based on Ti-and-Si-doped compounds. The combination of Titanium and Silicon nitrides grants the coating a truly high hardness and refractariety with increased resistance to thermoxidation. HSN2 is specially indicated for mechanizing quenched alloys to hardnesses greater than 55 HRC.

Benefits of the coating HSN2

  • High hardness and wear resistance.
  • Maintains the silhouette of the cutting's edge.
  • Mechanized alloys for dies and moulds which hardness is greater than 60 HRC.
  • High oxidation temperature.
