Ordinary stainless steel screws (take austenitic stainless steel as an example), the tissue structure will transform to martensite during production, thereby generating micro-magnetism, so the produced screws are magnetic. In some usage environments, the screws must not be a little magnetic, and non-magnetic screws are required. At this time, we need to spend some effort on degaussing.

Generally speaking, Stainless steel fasteners suppliers common method is to do high-temperature solution treatment for stainless steel screws to restore the austenite structure on the inner surface of the screw, so as to demagnetize and obtain stainless steel non-magnetic screws. However, it should be noted that the mechanical properties of the screws after solution treatment will change, such as the lower degree of finish and greater toughness. If you have requirements for these points, you must carefully consider whether to do solution treatment.
