(2)Industrial chrome plating names

  1. Industrial chrome plating of at least 20 µm thickness on an iron and steel substrate, buffing before plating, grinder polishing after plating, buffing after plating, with the final surface roughness of Ra1.6 µm
    EP-Fe/ICr20/1BF,2G,2BF (Ra1.6)
  2. Industrial chrome plating of at least 10 µm on an iron and steel substrate, liquid honing before plating
    EP-Fe/ICr10/1LH

(3)Plating symbols

"I" indicating industrial application is added before Cr (chrome plating) for plating symbols. This table summarizes the symbols representing pre/post plating processes.
