After some more reading, it seems that magnetic SS is really only worth steel price anyway. So I guess it doesn't matter what's under the brass plating, as it should go in with the ferrous. Correct?

Although some people mentioned that they toss magnetic SS in with SS that isn't. Is this one of those "ask your yard" things?

I am sorry. I really am reading all around to try to figure these things out without bothering anyone.

I did come across the Magnetic SS thread with the teen scrapper talking in dense text-speak, which was both amusing and a tad depressing. I don't know what he was saying either, and I DO text on my phone.
