How to convert fine brush finish into coarse brush finish on SS304 sheet? [India] 

May 5, 2007

I have SS304 1.2mm thick sheet parts (Size 128 mm x 230mm). The sheet already has a brush finish on it when I bought it. However, the brush finish on it is very bright and fine, while my other components which ultimately have to be assembled along with this item have coarser and less bright finish compared to this.
Please suggest how I can convert this fine brush finish into more dull & coarse finish?

Thank you in anticipation.

This would be done mechanically rather than chemically, Rishi. You would probably use scotch brite or sandpaper on a large flat belt sanding machine. As in everything else, skill and experience help; so you may want to contract it out.
