Why is stainless steel magnetic?
Answer: People often use magnets to detect the qualities of stainless steel. The magnet does not attract the goods without magnetism, but it is considered to be a fake. In fact, this is an extremely one-sided and unrealistic method of error discrimination.

Austenitic stainless steel is non-magnetic or weak magnetic; martensitic or ferritic stainless steel is magnetic. However, austenitic stainless steel after cold working, the structure of the processing part will also change to martensite. The greater the degree of deformation, the more martensite transformation, the greater the magnetic. The product material will not change. a more professional method should be used to detect the material of stainless steel. (spectral detection, stainless steel discrimination liquid detection).

2. Why does stainless steel rust?

Answer: a. dust containing other metal elements or attachments of heterogeneous metal particles are stored on the surface of stainless steel. in humid air, the condensed water between the attachments and stainless steel connects the two into a micro battery, causing electrochemical reaction, the protective film is damaged, called electrochemical corrosion.
B. stainless steel surface adhesion of organic-juice (such as vegetables, noodles soup, phlegm, etc.), in the case of water and oxygen, constitute organic-acid, long time organic-acid on the metal surface corrosion.
C. stainless steel surface adhesion contains acid, alkali, salt substances (such as the decoration of the wall of alkaline water, lime water splash), causing local corrosion.
      D. in the polluted air (such as containing a large number of sulfide, carbon oxide, nitrogen oxide atmosphere), the formation of sulfuric acid, nitric acid, acetic acid liquid point, cause chemical-corrosion.
