Why does stainless steel have magnetism?
Stainless steel is nonmagnetic only in theory, and is also made of material. The theory of austenite is non-magnetic, but the ferrite itself is strong magnetic.
In addition, austenitic stainless steel wire containing magnetic, is related to its processing technology, austenitic stainless steel raw materials are non-magnetic, but after processing, some finished products will have a weak magnetic.
