Stainless steel cleaning and maintenance methods

Views: 1    

The use of stainless steel has become more widespread with the development of the economy. People are closely related to stainless steel in their daily lives. However, many people do not know much about the performance of stainless steel, and they know even less about the maintenance of stainless steel. 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. In nature, it is in the form of a more stable oxide. In other words, although stainless steel has different oxidation degrees according to different usage conditions, it is eventually oxidized. This phenomenon is usually It's called corrosion. All metal surfaces exposed to a corrosive environment undergo electrochemical reactions or chemical reactions and are uniformly corroded. Parts of the passive film on the surface of stainless steel with weak corrosion resistance will form pitting corrosion reactions due to self-excited reactions, resulting in small holes. In addition, chlorine ions will approach, forming a very corrosive solution, and accelerating the speed of the corrosion reaction. There is also intergranular corrosion and cracking inside stainless steel, all of which have a destructive effect on the passivation film on the surface of stainless steel. Therefore, the stainless steel surface must be cleaned and maintained regularly to maintain its gorgeous surface and extend its service life. When cleaning the stainless steel surface, you must be careful not to scratch the surface. Avoid using washing liquids with bleaching ingredients and abrasives, steel wool, grinding tools, etc. In order to remove the washing liquid, rinse the surface with clean water at the end of the washing.
