Friends who understand the fastener industry know that carbon steel screws are magnetic, while stainless steel screws are slightly magnetic.As it is inherently weakly magnetic, that stainless steel screws can eliminate magnetism ?Follow the stainless steel screw manufacturers to take a look:

Ordinary stainless steel screws ( austenitic stainless steel as an example ), in the production of the organizational structure will be transformed to martensite, which produces a micromagnetism, so the screws produced are magnetic.And some of the use of the environment to go screws can not have a little magnetism, the need for non-magnetic screws, then this time we need to spend some effort to do demagnetization work.

In general, we commonly used method is to do high-temperature solid solution processing of stainless steel screws to gray the austenitic structure of the inner surface of the screws, thereby demagnetizing the magnetic, stainless steel non-magnetic screws.However, it should be noted that, after solid solution treatment of the screw mechanical properties will be changed, such as their own acidity becomes low, toughness becomes large.If you have requirements on these points, you should carefully consider whether to do solid solution treatment.
