​Two little knowledge about hardware stainless steel fasteners

It can be said that fasteners using stainless steel as a material have 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, in fasteners Among the firmware solutions, it is still one of the more economical.

Problems with stainless steel magnetism of fasteners

If stainless steel is used as the main material for fasteners, you must also understand the magnetic properties of stainless steel itself. Stainless steel is generally considered to be non-magnetic, but in fact austenitic series materials may become magnetic to a certain extent after certain processing techniques. However, it is incorrect to think that magnetism is the standard for judging the quality of stainless steel fasteners. precise.

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

The use of nickel in fasteners

In the process of using stainless steel as material, fasteners used to rely more on the use of nickel. However, as the global price of nickel increases, 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 searched for alternative materials and produced low-nickel stainless steel fasteners.
