What are the corrosion factors of stainless steel plates
Stainless steel plate is a kind of corrosion products is not easy, unless it’s some serious condition actually not impossible to achieve in any products from corrosion, if our stainless steel plate from corrosion are likely to affect the normal use of it, so in order to avoid this situation and we need to do some preventive measures, the following we first to get to know what are the factors from corrosion of stainless steel plate?
Electrochemical corrosion
Stainless steel plate due to contact with carbon steel caused by scratch, and then form a galvanic cell with corrosive medium this will produce electrochemical corrosion.If the pickling passivation effect is not good, it will also make the passivation film on the plate surface not uniform or too thin, which is also easy to produce electrochemical corrosion, slag cutting, splashing and other easy to rust substances attached to the plate, and then form a galvanic cell with the corrosive medium, resulting in electrochemical decay.Pickling passivation Cleaning is not clean, resulting in the remaining pickling passivation solution and the plate produced chemical corrosion products, and then formed electrochemical corrosion with the plate.

Chemical corrosion
Under certain conditions, many adhere to the surface of the stainless steel plate oil, dust or acid, alkali, salt and so on will be transformed into corrosive media, and some components of the plate chemical reaction, and chemical corrosion and rust.Cleaning, pickling and passivation are not clean enough, resulting in the retention of residual liquid, which directly corrode the plate.The surface of the plate is scratched, resulting in the destruction of the passivation film, so that the protection ability of the plate is reduced, easy to react with the chemical medium, chemical corrosion and rust.
