It is often believed that the magnet adsorption of stainless steel, to verify its merits and authenticity, and do not smoke without magnetism, that is good, genuine; smokers are magnetic, is considered a fake fake. In fact, this is an extremely one-sided and unrealistic method of discrimination.
There are many kinds of stainless steel. They can be divided into several groups according to the organizational structure at normal temperature: E-BON the stainless steel specialist, Stainless Steel Milk Cup supplier china.
1, Austrian shape: such as 201, 202, 301, 304, 316 and so on;
2, martensite or ferrite type: such as 430, 420, 410 and so on;
3, austenite is non-magnetic or weak magnetic, 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?
The above mentioned austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, due to melting segregation or improper heat treatment, will cause a small amount of martensite Austenitic 304 stainless steel body or ferrite. In this way, 304 stainless steel will have a weak magnetic. E-BON the most excellent stainless steel company, which provide you withFlat Base Stainless Steel Muddler.
In addition, 304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensitic transformation, the greater the magnetic properties of steel. Like a lot of steel strips, the product is made up of 76 tubes, without obvious magnetic induction, producing 9.5 tubes. Due to the large deformation of the Ling bend, the magnetic sense is obvious, and the square tube produced by the utility model has larger deformation than the round tube, especially the folding part, the deformation is more intense, and the magnetism is more obvious.
In order to completely eliminate the magnetic properties of the 304 steel caused by the above reasons, the stable austenite structure can be recovered by the solution treatment at high temperature so as to eliminate the magnetism.
In particular, magnetic because it causes 304 stainless steel, and other materials such as stainless steel, carbon steel, magnetic 430 is not the same level, that is to say the magnetic steel 304 always showed a weak magnetic.
This tells us, if the stainless steel band is weak magnetic or completely without magnetism, should be identified as "304" or "316" material; if the same as carbon steel magnetic, showing strong magnetic, because the distinction is not 304 material.
