It is often assumed that magnets adsorb stainless steel, verify their advantages and disadvantages, and do not absorb no magnetism. They think it is good, the price is genuine; if the suction magnet is magnetic, they think it is counterfeit fake. In fact, this is an extremely one-sided, unrealistic error discrimination method.
  
There are many kinds of stainless steel, which can be divided into several types according to the structure at normal temperature. E-BON the most excellent stainless steel company, which provide you with Professional Black Boston Cocktail Shaker
  
1. austenitic-type: 304, 321, 316, 310; 2. martensite or ferrite, such as 430, 420, 410; austenitic-type is non-magnetic or weak magnetic properties, martensite or ferrite is magnetic.    

Most commonly used as a decorative tube plate is austenitic stainless steel 304 material is generally non-magnetic or weakly magnetic, but fluctuations in chemical composition caused by smelting or processing of different magnetic properties may also appear, but this can not be considered to be counterfeit or substandard, what is the reason? 
   
As mentioned above, austenite is nonmagnetic or weak magnetic, while martensite or ferrite are magnetic. Due to segregation or improper heat treatment during smelting, a small amount of martensite or ferrite can be formed in Austenitic 304 stainless steel. In this way, the 304 stainless steel will have a weak magnetic field.   

In addition, the microstructure of 304 stainless steel will transform to martensite after cold processing. The greater the degree of cold working deformation, the greater the transformation of martensite, the greater the magnetism of steel. Like a batch of steel strip, the production of 76 tubes, no obvious magnetic sense, production of 9.5 tubes. Because of the larger magnetic sense of the cold bending deformation, the rectangular tube of the producer is larger than the round tube, especially the angle section.  

In order to completely eliminate the magnetic properties of 304 steel caused by the above reasons, the stability of austenite can be recovered by high temperature solution treatment, thus eliminating magnetic properties.  E-BON the stainless steel specialist, oem ice cube supplier.  

In particular, it is suggested that the magnetism of the 304 stainless steel caused by the above causes is not the same level as that of the other materials, such as 430 and carbon steel, that is to say, the magnetism of the 304 steel always shows the weak magnetism.   
This tells us that if the stainless steel strip is weakly magnetic or completely magnetic, it should be judged to be 304 or 316 material. If it is the same as the magnetism of carbon steel, it shows strong magnetism, because the discrimination is not 304 material.   

We suggest that the purchase of stainless steel products should have the credibility of the manufacturers of the products, do not be cheap, beware fooled.
