Fasteners using stainless steel as the material, it can be said that no matter in the manufacturing, use or treatment of each link has a great advantage, so although the cost of fasteners using stainless steel as the material itself is higher, the life cycle is relatively short, but in the fastener solution, it is still a more economical one.

 

 

Magnetic properties of stainless steel fasteners
 
If fasteners use stainless steel as the main material, they also need to understand the magnetic problems of stainless steel itself. Stainless steel is generally considered to be non-magnetic, but in fact, austenite series materials after a certain processing technology, it is possible to appear a certain magnetic, but if this is considered to be magnetic stainless steel fastener quality criteria is not accurate.
 
When selecting fasteners, whether the stainless steel material is magnetic or not does not indicate the quality of the high or low, in fact, some chrome manganese stainless steel is not magnetic stainless steel. Chromium manganese stainless steel can not replace 300 series stainless steel in stainless steel fastener, especially in high medium corrosive working environment.
 
Use of nickel in fasteners
 
Fasteners used to rely more on the use of nickel in the use of stainless steel, but the price of fasteners has also been greatly affected by the rise in global nickel prices. In order to alleviate the cost pressure and improve the competitiveness of fasteners, the fasteners manufacturers have especially looked for alternative materials and produced low-nickel stainless steel fasteners.
