Anodized look and texture using stainless steel?


I customise computer cases (Painting of stainless steel, and anodizing aluminum, etc..) Recently I was asked if I could anodize a case, but I could not because it was stainless. I am curious if there is a way to give the anodized look and texture of aluminum on stainless. Any answers would be appreciated.

For the record, stainless steel can be anodized, but only via proprietary processes such as are offered by Prismatic Stainless Steel [B&M Finishers].

When aluminum is brightened before anodizing it is difficult to distinguish by eye from stainless steel although aluminum is a little whiter, and stainless a little bluer. Look at a truck with polished "diamond plate" and guess whether it is stainless or aluminum--if you're like me you'll be wrong about 50 percent of the time.

So what I think you are associating with aluminum is the matte finish more than the color. In aluminum processing this is a result of chemical etching, but I think it is obtainable on stainless by blasting.

You could find a dyed coatings that simulate different anodized colors. A problem with this is certain colors degrade and fade quickly when exposed to light.

Good luck,
