4x8 Inch Inox 304 316 Stainless Steel Sheet is actually a product that is not prone to corrosion. Except in some serious cases, it is impossible for any product to be corrosion-free. If our 4x8 Inch Inox 304 316 Stainless If the Steel Sheet is corroded, it may affect its normal use, so we still need to take some preventive measures to avoid this happening. Let's first understand the factors that cause the 4x8 Inch Inox 304 316 Stainless Steel Sheet to be corroded. Which ones?


1) Electrochemical corrosion

4x8 Inch Inox 304 316 Stainless Steel Sheet is scratched due to contact with carbon steel parts, and then forms a galvanic cell with the corrosive medium, which will produce electrochemical corrosion. If the pickling and passivation effect is not good, the passivation film on the surface of the plate will be uneven or too thin, which will easily cause electrochemical corrosion, cutting slag, splash and other rust-prone substances to adhere to the plate, and then form with corrosive media. galvanic battery, thus producing electrochemical corrosion. If the pickling and passivation is not cleaned thoroughly, the remaining pickling and passivation residue will produce chemical corrosion products with the plate, and then form electrochemical corrosion with the plate.


2) Chemical corrosion

Under certain conditions, a lot of oil, dust, acid, alkali, salt, etc. attached to the surface of the stainless steel plate will be converted into corrosive media and chemically react with some components in the plate, resulting in chemical corrosion and rust. Cleaning, pickling and passivation are not clean enough, resulting in residual liquid remaining, which directly corrodes the plate. The surface of the plate is scratched, resulting in the destruction of the passivation film, thus reducing the protective ability of the plate and easily reacting with chemical media, resulting in chemical corrosion and rust.
