Product Description

The hard chromium plating layer has excellent characteristics which combine the original properties of chromium metal with the advantages of erectro-deposits. The main features of hard chromium plating are as follows:

1. Extermely high hardness of HmV (Micro Vickers)

800 to 1100 (cf. gray cast iron 220 to 270)

2. High melting point of approx. 1800℃ (cf. cast iron 1200℃ )

3. Good thermal conductivity and corrosion resistance.

4. Low friction factor and excellent wear resistance. Such features are very effective in preventing piston ring wear.
