Black Oxide on 410 Stainless screws
I am a Buyer for a company that manufactures gauges for high performance race and show cars. We have been having problems with the plating on some of the Stainless Steel screws we use. The screws are made from 18-8 Stainless and we want to use a Black Oxide finish.
Because these screws are sometimes used on white face gauges, we like to have them as dry as possible to eliminate any oil marks on the dial. When we have them plated using no wax or oil, they don't look very black.
There is another part we use that is made from 430 Stainless with a Black Oxide finish. Again, we specify no wax or oil in the plating process, but we never have any problems with these. Both are done by the same plater.
The manufacturer will not make the screw from 430 because it is too soft to use in a screw machine, but has offered to use 410. Is 410 easier to plate than 18-8? I know both 410 and 430 are magnetic, but 18-8 is not. Does that affect the plating process?
I am open to any suggestions you might have on this subject.
Thank You,Scott Eakens
