Glossy black finish on carbon steel
+++++
Hello,
I currently have some carbon steel tubes that have been heat-treated
and welded.
Traditional coating for them has been black-oxide, however some
customers would like to see a glossy black finish on them. I have
tried polishing the surface before plating(black-oxide), the results
weren't glossy enough. Of course I'm looking for something cost
competitive with the black-oxide. Any help would be greatly
appreciated.

You may have tried polishing, Gene, but you didn't try hard enough
:-)
Don't give up. A high quality black oxide on a highly polished
surface can give you a finish that looks like a jewel.

Black oxide is traditionally oiled or waxed for better corrosion
resistance. Look at a black wax.

Oil it sparingly with any eddible oil (
Linseed Oil [link is to product info at Rockler] is best)or 20%
shellac solution,then heat it slowly to 4oo C.Repeat if need,and then
lacquer it.
Good luck!
