In daily life, stainless steel pipe is not magnetic in fact is the basic common sense of life, let alone 304 stainless steel pipe, stainless steel pipe is magnetic or not is not a sentence to be able to say. As a very common material in life, 304 stainless steel pipe in the end there is no magnetism?
Sometimes even the scrap collector will carry a suction stone, used to test the material is not stainless steel, so as to avoid receiving the wrong material. This can actually only be borrowed simply in life. Iron is magnetic, so it can be attracted by the suction stone, and stainless steel pipe with other elements, and in the smelting process to form a different crystal structure, so it will affect the magnetic performance of the final product. Most varieties of stainless steel do not have magnetic properties, but some specifications of stainless steel is magnetic. 304 stainless steel pipe is the use of 304 stainless steel processed into steel pipe, this material is usually non-magnetic or weakly magnetic. However, in the production and smelting process of some accidental factors, will also make the end product microstructure changes, resulting in a weak magnetic. Therefore, it can not be said in general that 304 stainless steel pipe is not magnetic.
