1. Why is stainless steel magnetic?
     A: People often use magnets to check the quality of stainless steel. The magnet does not suck without magnetism, and the goods are really cheap. On the contrary, they are considered fake counterfeit goods. In fact, this is an extremely one-sided, unrealistic method of misidentification.

      Austenitic stainless steel is non-magnetic or weakly magnetic; martensitic or ferritic stainless steel is magnetic. However, the austenitic stainless steel is cold worked, and the microstructure of the processed part is also transformed into martensite. The greater the degree of processing deformation, the more martensite transformation and the greater the magnetic properties. The material of the product does not change. A more professional method should be used to detect the material of stainless steel. (Spectral detection, stainless steel identification solution detection).

2. Why does stainless steel rust?

     Answer: a. The surface of stainless steel contains dust or other metal particles attached to other metal elements. In humid air, the condensed water between the attached material and the stainless steel connects the two into a micro battery, causing electricity. In the chemical reaction, the protective film is destroyed, which is called electrochemical corrosion.
     b. The surface of the stainless steel adheres to the organic juice (such as melon, noodle soup, glutinous rice, etc.), and in the case of water and oxygen, constitutes an organic acid, and the organic acid corrodes the metal surface for a long time.
     c. The surface of the stainless steel adheres to acid, alkali, and salt substances (such as alkali water and stone water splashing on the wall), causing local corrosion.
     d. In polluted air (such as the atmosphere containing a large amount of sulfide, carbon oxide, nitrogen oxide), in the case of condensed water, sulfuric acid, nitric acid, acetic acid liquid point is formed, causing chemical corrosion.
