Stainless steel fastener material related knowledge

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

Stainless steel magnetic problem of fasteners

If you use stainless steel as the main material for fasteners, you must also understand the magnetic problems of stainless steel itself. Stainless steel is generally considered to be non-magnetic, but in fact, after a certain processing technology, austenitic series materials may appear to be magnetic. precise.

When selecting fasteners, whether stainless steel materials are magnetic does not indicate their quality. In fact, some chromium-manganese stainless steels are stainless steels that are not magnetic. 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, fasteners used to rely on the use of nickel. However, with the global price increase of nickel, the price of fasteners has also been greatly affected. In order to alleviate the cost pressure and improve the competitiveness of fasteners, fastener manufacturers especially searched for alternative materials and produced low-nickel stainless steel fasteners.
