According to our production experience. The stainless steel can be absorbed by the iron magnet after stamping.

Generally, in the state of sheet or coiled plate, the material without deep processing will not be attracted by the magnet. However, after deep drawing, some parts of 304 will be transformed into martensitic structure, showing weak magnetism, which may be attracted by the magnet at this time.

Therefore, if the plate can be absorbed by the magnet, it must not be 304. If the product can be absorbed by the magnet, it must not be demagnetized.
