Two little knowledge of hardware stainless steel fasteners
Fasteners are made of stainless steel. 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, it can be Among the firmware solutions, it is still a relatively economical one.
Stainless Steel Magnetic Issues for Fasteners
If stainless steel is used as the main material for fasteners, it is necessary to understand the magnetic properties of stainless steel itself. Stainless steel is generally considered to be non-magnetic, but in fact, austenite series materials may appear magnetic to a certain extent after a certain processing process, but if it is considered that magnetic is the standard for judging the quality of stainless steel fasteners, it is not precise.
When selecting fasteners, whether the stainless steel is magnetic does not indicate its quality. In fact, some chrome-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 highly corrosive working environments.
Use of Nickel in Fasteners
In the process of using stainless steel as the material, fasteners used to rely on the use of nickel elements, but with the global price increase of nickel elements, the price of fasteners has also been greatly affected. In order to reduce the cost pressure and improve the competitiveness of fasteners, fastener manufacturers have looked for alternative materials and produced low-nickel stainless steel fasteners.
