  Fasteners use stainless steel as the material, which can be said to have great advantages in all aspects of manufacturing, use or processing. Therefore, although the cost of using stainless steel as the material of fasteners is relatively high and the cycle life is relatively short, it is Among the firmware solutions, it still belongs to the more economical one.


   Stainless steel magnetic problem of fasteners


   If stainless steel is used as the main material for fasteners, it is necessary to understand the magnetic problems of stainless steel itself. Stainless steel is generally considered to be non-magnetic, but in fact, austenitic series materials may appear to be magnetic after a certain processing technology. However, if magnetism is considered to be the standard for judging the quality of stainless steel fasteners, it is not precise.


   When selecting fasteners, whether the stainless steel material is magnetic does not indicate its quality. In fact, some chromium-manganese stainless steels are non-magnetic stainless steels. Chromium-manganese stainless steel in stainless steel fasteners cannot replace the use of 300 series stainless steel, especially in high-medium corrosive working environments.


  The use of nickel in fasteners


   In the process of using stainless steel as a material for fasteners, it used to rely more on the use of nickel. However, as the global price of nickel has risen, the price of fasteners has also been greatly affected. In order to alleviate cost pressure and improve the competitiveness of fasteners, fastener manufacturers have specifically looked for alternative materials and produced low-nickel stainless steel fasteners.
