Two Knowledge of Hardware Stainless Steel Fasteners
Fasteners using stainless steel as material can be said to have great advantages in all aspects of manufacture, use or treatment. Therefore, although the cost of fasteners using stainless steel as material itself is higher and the life cycle is relatively short, it still belongs to a more economical one in the solution of fasteners.
Magnetic problems of stainless steel fasteners
If stainless steel is used as the main material for fasteners, the magnetic properties of stainless steel itself should also be understood. Stainless steel is generally considered to be non-magnetic, but in fact, austenitic series materials after a certain processing technology, it is possible to have a certain degree of magnetic, but it is also inaccurate to consider magnetism as a criterion for judging the quality of stainless steel fasteners.
In the selection of fasteners, whether the stainless steel material has magnetism does not indicate its quality. In fact, some Chromium-Manganese stainless steel is just non-magnetic stainless steel. Chromium-manganese stainless steel in stainless steel fasteners can not replace the use of 300 series stainless steel, especially in high-medium corrosive working environment.
Use of Nickel in Fasteners
Fasteners used to rely more on nickel in the process of using stainless steel as material, but the price of fasteners has also been greatly affected by the rising global price of nickel. In order to alleviate the cost pressure and improve the competitiveness of fasteners, manufacturers of fasteners have specially searched for alternative materials to produce stainless steel fasteners with low nickel content.
