Stainless turned copper

[righter13]

I've been tumbling my k baffles in stainless media and now they're starting to turn a copper color. Any advice?

I would assume you are removing some type of coating or plating on them

First thought is either a reaction or removal

That would work if my goal was to get them black

You removed the chrome plating, chromium is usually plated over copper and nickel on steel. What you are seeing is the thicker base layer of copper that is plated to the steel (chromium doesn't stick to steel)

On chrome, solvents are MUCH safer than tumbling. Chromium is non-reactive, so even nasty solvents don't bother it.

So stainless steel is actually copper at the base? Is there any structural damage done?

Most likely an alloy steel with plating. Stainless steel generally cuts the same color.
What specific media did you use and what is the ISO of the material?

Kestrel Baffles? I have not tumbled mine yet. That is odd. I wonder if HTA would respond to that satisfactorily?
