Kirin Coat S

Before and after special nitriding, there is no change in surface condition regardless of whether it is mirror-surface or texture processed. Thus, polishing after nitriding can be omitted.

Features

  1. No white layers are generated by special nitriding, while surface hardness and nitriding depth are equivalent to those of conventional methods.
  2. Since there is no change in surface roughness before and after the treatment, finish polishing is unnecessary.
