Stainless steel may exhibit magnetism depending on its microstructure. Austenitic grades such as 304 and 316 are typically non-magnetic, while ferritic (430) and martensitic (410) grades are magnetic. In some cases, cold working processes like bending or stamping can induce slight magnetism in 304/316. Magnetism does not indicate quality—it reflects material structure and processing history.
