1.The surface of the stainless steel plate offer the dust containing other metal elements, or heterogeneous metal particles such as attachments, appeared in the humid air, its attachments and condensed water between direct and stainless steel plate, when happen between micro batteries, will cause a series of chemical reactions, the protective film on the surface of the stainless steel plate can also severely damage, so we can call the electrochemical corrosion.
2.When the surface of stainless steel plate stick organic juice, such as our common noodle soup, phlegm and melon vegetables, in the case of water and oxygen, will form organic acid, lasting longer time, organic acid will cause certain corrosion on the surface of the metal.
3.Or stainless steel plate surface adhesion with alkali, acid and salt and other substances, such as decoration can be used to the lime water and alkaline water, can cause local corrosion of stainless steel plate.
4.In the polluted air, the stainless steel plate encountered condensed water, formed nitric acid, sulfuric acid, acetic acid and other liquid points, eventually leading to the surface of a more serious chemical corrosion phenomenon.
The above mentioned four cases, can cause serious corrosion of the surface of stainless steel plate, so we in the daily use of stainless steel plate, should try to avoid the appearance of such phenomenon.
