Gas soft nitriding Treatment

A low cost treatment for any shapes of products

Features

  1. A compound layer formed during the treatment is dense with high hardness.
  2. Since this is a low temperature treatment, dimensional change can be controlled to a minimum.
  3. The compound layer formed has very few pinholes, cracking or other defects.
  4. Since corrosion resistance is remarkable, it can be used without plating.
