Magnets are often used to distinguish whether stainless steel is true or false. If magnets are not attractive, such stainless steel is considered good. If magnets are attractive, it means that they are counterfeit. But this method of discrimination is one-sided and impractical.

Generally speaking, magnetism is determined by many factors, such as the arrangement of molecules. Magnetism refers to the physical properties of materials. If stainless steel is absolutely non-magnetic, this statement is incorrect. Ferritic stainless steel has a little magnetism.

Carbon stainless steel is mostly used to make household metal products because of its low requirements, because it contains more carbon and less other alloying elements, so it is still somewhat magnetic.
