The use of 316 stainless steel plates has become more widespread with the development of the economy, and people are closely related to stainless steel in their daily lives. However, many people do not have much understanding of the performance of stainless steel, and they know less about the maintenance and upkeep of 316 stainless steel plates. Many people think that stainless steel will never rust, but in fact, stainless steel has good corrosion resistance. The reason is that a passivation film forms on the surface, which exists in a more stable oxide form in nature. That is to say, although stainless steel has different degrees of oxidation according to different usage conditions, it is ultimately oxidized, which is commonly referred to as corrosion. All metal surfaces exposed in corrosive environments undergo electrochemical or chemical reactions, resulting in uniform corrosion.
The areas with weak corrosion resistance in the passivation film on the surface of 316 stainless steel plate form pitting corrosion reactions due to self-excited reactions, forming small pores, and with chloride ions approaching, forming a strong corrosive solution, accelerating the rate of corrosion reactions. There is also intergranular corrosion cracking inside stainless steel, all of which have a destructive effect on the passivation film on the surface of stainless steel plates. Therefore, regular cleaning and maintenance must be carried out on the surface of stainless steel to maintain its luxurious appearance and extend its service life.
