Why does stainless steel have magnetism? When 304/316 stainless steel is cold - processed, its microstructure turns into martensite. The more the cold - processing deformation, the more martensite forms and the stronger the magnetism. A straight stainless - steel support has no obvious magnetism. But when bent into a rectangle or circle, large cold - bending deformation makes it magnetic, especially at the corners. This doesn't affect the cup's use.
