NC3220 [Grade for all applications of steel]

  • NC3220 covers a wide application range for all kinds of steels (carbon steel, alloy steel, forged steel, rolled steel,
    tool steel, mild steel, bearing steel and other special steels) in both continuous and interrupted machining.
  • New substrate and new coating layer with good wear resistance provides longer tool life preventing plastic
    deformation in high speed and high temperature machining.
  • Improved coating layer with superior adhesion and new surface treatment provides excellent welding resistance and
    chipping resistance that leads to stability of machining and improvements in productivity .
  • Increased lubrication of coating layer improves the surface finish and reduces the cutting load to increase wear
    resistance.
Coating structure
  • TiN layer with good surface roughness and welding resistance
  • Al₂O₃ layer with oxidation resistance at high temperature and plastic deformation resistance.
  • Bonding layer with excellent chipping resistance due to improving adhesion.
  • Fine columnar MT CVD-TiCN with toughness and wear resistance.
  • Exclusive substrate material for coating improving wear resistance.
