Why does 321 stainless steel flat steel also carry magnets? People often think that magnets absorb stainless steel, verify its advantages and disadvantages and authenticity, do not attract non-magnetic, think it is good, the goods are genuine; the smoker 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 structure at room temperature:
1. Austenitic type: such as 304, 321, 316, 310, 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 for decorative tube sheets are austenitic 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, but this cannot be considered as Counterfeit or unqualified, what is the reason?
