Two tips on hardware and stainless steel fasteners

Magnetic issues with stainless steel fasteners

If stainless steel is used as the main material for fasteners, it is also important to understand the magnetic properties of the stainless steel itself. Stainless steel is generally considered non magnetic, but in reality, austenitic series materials may exhibit certain magnetism after certain processing techniques. However, it is inaccurate to assume that magnetism is the standard for judging the quality of stainless steel fasteners.

When selecting fasteners, whether the stainless steel material has magnetism does not indicate its quality. In fact, some chromium manganese stainless steels are non magnetic stainless steels. Chromium manganese stainless steel cannot replace the use of 300 series stainless steel in stainless steel fasteners, especially in high medium corrosive working environments.

Use of nickel element in fasteners

In the process of using stainless steel as the material for fasteners, they used to rely more on the use of nickel element. However, with the global price increase of nickel element, 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 sought alternative materials and produced low nickel stainless steel fasteners.
