Surface Finish Spec

[chipgt500]

I have a drawing (in Japanese) that calls for a surface finish of "SBCr". The material is Nobinite CD-5 (similar to Invar 36). Does anyone know what process "SBCr" is referring to?

The only thing I can find on a quick Google search is some type of powder coating.

I was able to figure it out. It is Black Chrome plating, apparently used often in Japan. Now I just need to find a spec...

Good luck.
I have tried searching for their specs and usually hit a wall.
If you work with a China mfg plant, they may have a copy.
