NAK80 Steel Round Bar Sheet Plate Material

NAK80 steel material is a prehardening plastic mold steel. Out of the factory, the hardness can be reached 37-43 HRC. Without S, it has good mirror polish and EDM. After the production of special smelting, it will get high cleanness and stable performance. NAK80 steel has great polishing property, it no needs heat treatment. Perfect machinability and lower surface roughness, the hardness is balance in anywhere. After the processing of spheroidizzing annealing, its machinability will be better. Add the elements of Vanadium and Molybdenum in a special way, the wear resistance is up to the next level. And the toughness also is good, with the great mechanical properties, you do not need to worry about the problem of fracture.

Quick Quote

What Is NAK80 Used for?

The common uses of NAK80 steel material as below:

  1. Mirror Polishing Mold
  2. TV Light Filter
  3. Cosmetics Boxes
  4. Office Automation Equipment
  5. The Mold of Transparency Product of Car, Camera, Computer and more
  6. Coining Die
  7. Shear, Blades for Woodworking
  8. Cold-heading Dies

Processing Methods of NAK80

Cutting Tool

The hardness and cutting resistance of NAK80 are higher than others. So we suggest using the M2 high speed steel (SKH9) or superhard alloy P40.

Drilling

During the drilling, the bigger size of holes must with lower cutting speed.
