I've acquired three 50 gallon steel drums which I think were used in hot
water systems.
I need to know whether or not they are stainless steel (as opposed to
non-stainless). How can I test them?
Stratis.
A magnet will not stick to food grade stainless.
Note that there are lots of corrosion resistant steel alloys, some are
magnetic.
