Can stainless steel screws be eliminated magnetism?

Publish time: 24 Mar 23

Customers who understand the fastener industry know that carbon steel screws are magnetic, and stainless steel screws with a little magnetic. So recently a customer asked whether stainless steel screws can be eliminated magnetism? Follow the stainless steel screw manufacturer to have a look:

Ordinary stainless steel screws (take austenitic stainless steel as an example), at the time of production, the organizational structure will be transformed to martensite, resulting in micro magnetism, so that the produced screws have magnetism. And some environment will require the screws can not have a little magnetic, need no magnetic screws, so at this time we need to spend some time to make them without magnetic!

Generally speaking, our commonly used method is to do high temperature solid solution treatment for stainless steel screws to restore the austenitic structure of the inner surface of the screws, so as to eliminate magnetism, get stainless steel magnetic screws. However, it is important to note that the mechanical properties of the screws after solution treatment will be changed, such as their own strength becomes lower, toughness becomes larger. If you have requirements for these points, you should carefully consider whether to do solid solution treatment.
