Why is the stainless steel sink magnetic

The stainless steel plate itself is not magnetic, but in the process of stretch forming, the sheet metal crystal structure is deformed by high-pressure extrusion, and a small amount of martensitic structure will be generated. This structure has slight magnetism, and the magnetic properties will be larger when the sheet metal deformation is large. So, the basin body tensile part with a little magnetic, especially the maximum tensile deformation of four is also slightly rounded, and magnetic. The tensile deformation of the panel is small and almost not magnetic. This magnetization does not affect the function of the tank, nor does it affect health, and the time is long, and it will weaken or even disappear. At present, some products on the market are not magnetic, because they are demagnetized to cater to some unexplained consumers.
