What are the factors of corrosion of stainless steel plate?

Stainless steel plate is a product that is not prone to corrosion unless it is some serious cases any product is impossible to do without corrosion, if our stainless steel plate is corroded then it may affect its normal use, so we need to do some preventive measures to avoid the occurrence of this situation, the following we will first understand the factors of corrosion of stainless steel plate have What?

(A) electrochemical corrosion

Stainless steel plate due to contact with carbon steel parts caused by scratching, after the formation of primary cells with corrosive media which will produce electrochemical corrosion. The pickling passivation effect is not good then will also make the plate surface passivation film is not uniform or too thin, so it is also easy to produce electrochemical corrosion, cutting slag, splash, and other rust-prone materials attached to the plate, after the formation of primary cells with the corrosive medium, thus producing electrochemical corrosion. The pickling passivation cleaning is not clean, resulting in the residue of pickling passivation and plate chemical corrosion generation, and then with the formation of plate electrochemical corrosion.

(B) chemical corrosion

Under certain conditions, many attached to the surface of the stainless steel plate oil, dust or acid, alkali, salt, etc. will be transformed into a corrosive medium, and some of the components of the plate chemical reaction, resulting in chemical corrosion and lead to rust. Cleaning pickling passivation is not clean enough to cause the residue to remain, thus directly corroding the plate. The surface of the plate is scratched, which leads to the destruction of the passivation film, so the protection ability of the plate is reduced, and it is easy to react with chemical media, resulting in chemical corrosion and rusting.
