I recently purchased a two roller adjustable grain mill which specifies 304 stainless rollers in the listing. When I received it, I checked the rollers with a magnet and it stuck to both of them (pretty sure 304 stainless is not magnetic). I'd rather not have rusted rollers sometime down the road. I have a message in with the merchant to clarify but looking at other options in case I send it back. Many mills look dubiously similar in construction to the one I purchased (Cereal Killer, Kegco, NB Hullwrecker) which makes me wonder which mills actually have stainless rollers.
If anyone gets some time, would you mind testing your mill rollers with a magnet and see if it sticks? If not, would you please post the model?
