Stainless steel plate subjected to corrosion of 304 stainless steel plate factors

Stainless steel plate is in fact 304 a kind of corrosion is not easy to produce products, unless it is some serious cases in fact, any product can not do 304 material to not be corroded, if our stainless steel plate is corroded, it may affect the normal use of 304 material, So in order to avoid this situation, we need to do some preventive measures.

Electrochemical 304 Corrosion.

Stainless 304 steel plate due to the scratch caused by contact with carbon steel parts, 304 stainless steel plate and corrosion medium formed galvanic cell, which will produce electrochemical corrosion 304 material, 304 pickling passivation effect is not good will also make the plate surface passivation film is not uniform or too thin, 304 material this is also easy to produce electrochemical corrosion, Splash and other easy to rust material 304 attached to the plate, after the corrosion medium 304 into the galvanic battery, 304 material resulting in electrochemical corrosion, pickling 304 passivation cleaning is not clean resulting in residual pickling passivation liquid and plate chemical corrosion products, and then the formation of electric 304 chemical corrosion with the plate.

Chemical 304 wood corrosion.

Under certain conditions, 304 less attached to the surface of the stainless steel plate oil, dust or 304 acid, salt and so on into the corrosion of 304 medium, and some of the components of the 304 chemical reaction, resulting in chemical corrosion and 304 rust, cleaning pickling passivation is not clean enough 304 resulting in residual liquid retention, thereby directly corrosion 304 plate, The 304 surface of the plate is scratched, resulting in the destruction of passivated 304 film, so that the protection ability of the plate is reduced by 304, easy to react with 304 chemical medium, 304 chemical corrosion and rust.
