Why Stainless Socket Head Cap Screw With Magnetic?
People often think that magnets absorb stainless socket head cap screw , verify their pros and cons and authenticity, do not absorb non-magnetic, think it is good, the goods are genuine; if the absorber is magnetic, it is considered a counterfeit fake. In fact, this is an extremely one-sided, unrealistic way of distinguishing mistakes. There are many types of stainless steel, which can be divided into several categories according to the organizational structure at room temperature: 1. Austenitic type: such as 304, 321, 316, 310, 201, etc.; 2. Martensite or ferrite type: such as 430, 420, 410, etc.; The austenite type is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic. Most of the stainless steels used as decorative tube sheets are austenitic type 304 materials, which are generally non-magnetic or weakly magnetic. However, magnetic properties may occur due to fluctuations in chemical composition or processing conditions due to smelting,...
