All edges and corners must be broken or have a small radius. The surface finish is not terribly critical, but the part is seen on the front of a piece of equipment so it should be reasonably good looking. It must be non-oxidizing / non-corroding. It cannot be painted or coated with something that would be removed or badly scuffed by light to moderate abrasion.
The part must be cheap, (Less than $.30 or so, $.50 max)
It must allow a magnet to stick to it, but it does not / should not be magnatized.
I was thinking a piece of 410 SST bar cut off and tumbled, but I can't find anybody selling 410 SST bar except McMaster Carr Unfortunately their price is about $18 per foot!!!!
Another choice would be 1018 CRS and have it nickle plated but I know nothing about plating. There are no holes in the part, so I wonder how it would be held for plating.
Any Ideas? - Thanks,
Once this is figured out, I need a hundred right away and then a thousand if it works properly.

I would use mild steel easily cut with a cold saw, pickle, tumble and phosphate coat. Problem is to many steps for your price range with a small number. As you noticed stainless is out with just material cost.
While a simple piece to make labor kills with a small job. Setup and cleanup are the same to do a 100 or 10,000 of this type of part.
