304 stainless steel how to identify?
Use magnets to identify. Ordinary steel has a strong magnetic, 304 stainless steel non-magnetic or weak magnetic (manufacturers in order to save costs, not in the cold processing after the corresponding heat treatment, eliminate magnetism), the same magnet close to ordinary steel and 304 stainless steel, can obviously feel the size gap between the two attraction.
