If you bend stainless 304 it will become magnetic. Thats why some sinks have magnictivity (is that even a word?) where they press the sink part into the flat sheet at the factory. i have bent some SS b4 and it became magnetic and some does not become magnetic. I always sell mine as clean stainless but because of my reputation at the yard they don't even check them.
Plus i learned at the new yard that lightly magnetic SS is considered just a different grade of stainless cause the magnet does a hard pull to steel compared to a slight pull from SS.
