The use of maintenance 316 stainless steel plates has become more and more extensive with economic development. People are closely related to stainless steel in daily life, but many people do not understand the performance of stainless steel, and even know the maintenance of 316 stainless steel plates. less. Many people think that stainless steel never rusts.
In fact, stainless steel has good corrosion resistance. The reason is that a passivation film is formed on the surface, and the passivation film essentially exists in the form of a more stable oxide. That is to say, although stainless steel differs in oxidation according to the usage conditions, it will eventually be oxidized. This phenomenon is commonly referred to as corrosion.
All metal surfaces exposed to corrosive environments will undergo electrified or chemical reactions and will be evenly corroded. The corrosion resistance of the passivation film on the surface of 316 stainless steel is weak. Due to the self-excited reaction, pitting corrosion is formed, and small holes are formed. In addition, the chloride ion is sealed, and a strong corrosive solution is formed to accelerate the corrosion reaction rate.
There are also intergranular corrosion cracks inside the stainless steel. All the cracks destroy the passivation film on the surface of the stainless steel plate. Therefore, the stainless steel surface must be cleaned and maintained regularly to maintain its beautiful surface and extend its service life.
