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 may will affect the normal use of it, so in order to avoid this situation and we need to do some preventive measures, Let's first understand the corrosion of stainless steel plate what are the factors?

1) Electrochemical corrosion

Stainless steel sheet due to contact with carbon steel parts caused by scratch, after the formation of galvanic cell with corrosive medium which will produce electrochemical corrosion. If the effect of pickling passivation is not good, the passivation film on the surface of the plate will be uneven or too thin, which is also easy to produce electrochemical corrosion, slag, splash 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, which leads to the chemical corrosion products between the remaining pickling passivation residue and the plate, and then the electrochemical corrosion is formed with the plate.

Two) chemical corrosion

Under certain conditions many attached to the surface of stainless steel plate oil, dust or acid, alkali, salt will be converted into corrosive medium, and some components of the plate chemical reaction, resulting in chemical corrosion and rust. Cleaning and pickling passivation is not clean enough to cause residual liquid retention, thus directly corroding the plate. The surface of the plate is scratched, which leads to 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.
