Protection And Maintenance Of Stainless Steel Plates

The use of stainless steel plates has become more widespread with the development of the economy. People are closely related to stainless steel in their daily lives. However, many people don't know much about the performance of stainless steel, and they know less about the maintenance of stainless steel plates. Many people think that stainless steel will never rust. In fact, stainless steel has good corrosion resistance.

　The reason is that a passivation film is formed on the surface, which exists in the form of a more stable oxide in nature. In other words, although the degree of oxidation of stainless steel varies according to the conditions of use, it is eventually oxidized. This phenomenon is usually called corrosion. All metal surfaces exposed in the corrosive environment undergo electrochemical or chemical reactions and are evenly corroded.

In the passive film on the surface of the stainless steel plate, where the corrosion resistance is weak, the pitting reaction is formed due to the self-excited reaction, resulting in the formation of small holes, and the chloride ion is close to form a strong corrosive solution, which accelerates the rate of the corrosion reaction . There is also intergranular corrosion cracking inside the stainless steel, all of which have a destructive effect on the passivation film on the surface of the stainless steel plate. Therefore, the stainless steel surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life.
