Why can stainless steel screw be attached magnetic？

Some customers have found that stainless steel screws get sucked up if they are sucked up with magnets. Why is that? The reason is that there have been some changes in the handling of stainless steel screws. Let's look at why stainless steel screws are magnetic.

1.After cold heading rolling, the molecular arrangement of stainless steel screws will be changed, resulting in micro magnetism, but this is only physical property, chemical property is not changed.

2.It is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel screws, steel should contain more than 18% chromium and 8% nickel content.

3.Stainless steel screw density of 7.93g /cm3, also known as 18/8 stainless steel, high temperature resistance 800 degrees, with good processing performance, high toughness, widely used in industrial and furniture decoration industry and food and medical industry.
