ㆍ Grade for all applications of steel
ㆍ New technology of surface treatment improves welding resistance and stability in machining.

Features

ㆍ 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
ㆍ New substrate and new coating layer with good wear resistance provides longer tool life preventing plastic deformation in high speed and high temperature machining

NV3220

ㆍ For medium machining of steel
ㆍ Universal grade combining substrate with wear resistance and toughness and coating with oxidation resistance and fracture resistance
ㆍ Special treatment on the outermost layer

Advantages

ㆍ 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 ㆍ Increased lubrication of coating layer improves the surface finish and reduces the cutting load to increase wear resistance.
