Why stainless steel roll rust

1, stainless steel surface deposit contains deposits of other metallic elements of dust or heterogeneous metal particles in the humid air, the condensate between the attachment and stainless steel, the two connected into a micro-cell, triggering the electrochemical reaction , The protective film is damaged, called electrochemical corrosion.Stainless Steel Sheets,Stainless Steel Coils-Miele Metal

2, stainless steel surface adhesion of organic juice (such as vegetables, noodles soup, etc.), in the case of water oxygen, organic acids, organic acids formed for a long time on the metal surface corrosion.310S stainless steel seamless pipe supply in China

3, stainless steel surface adhesion with acid, alkali, salt substances (such as the renovation of the wall of alkali water, lime water spray test) caused by local corrosion.SUS444 stainless steel pipe exporters

4, in polluted air (containing a large amount of sulfide, oxide, hydrogen peroxide in the atmosphere), the case of condensate, the formation of sulfuric acid, nitric acid, acetic acid point, causing chemical corrosion.eastasia metal,stainless steel sheet
