Stainless steel screws can be said to have great advantages in all aspects of manufacturing, use or handling. Therefore, although the fasteners are made of stainless steel, the cost is relatively high, and the cycle life is relatively short, but the solution of the screw fasteners is solved. In the program, it still belongs to a more economical one.

It is necessary to understand the magnetic problems of the stainless steel itself. Stainless steel is often considered not to be magnetic, but in fact, after a certain processing of austenitic materials, it is possible to have some magnetic properties.

Strictly speaking, if the magnetic quality is the standard for judging the quality of stainless steel fasteners, Too accurate. When the fasteners are selected, whether the stainless steel material is magnetic or not does not indicate the quality of the fasteners. In fact, some chromium-manganese stainless steels are stainless steels that do not have magnetic properties. Chromium-manganese stainless steel in stainless steel fasteners is not a substitute for the use of 300 series stainless steels, especially in high-media corrosive working environments.

Stainless steel screw fasteners have relied more on the use of nickel in the past, but as the price of nickel has increased, the price of fasteners has been greatly affected. In order to reduce the pressure on production costs and to improve the competitiveness of fasteners, companies that produce fasteners have searched for nickel-based alternative materials and produced low-nickel stainless steel fasteners, which in turn reduce production costs.
