Maintenance and characteristics of 316 stainless steel plate

Maintenance and characteristics of 316 stainless steel plate

Due to the addition of Mo element, 316 stainless steel plate has particularly good corrosion resistance, atmospheric corrosion resistance, and high-temperature strength, and can be used under harsh conditions; excellent work hardening (non-magnetic); excellent high-temperature strength; The solid solution state is non-magnetic; cold-rolled 316 stainless steel plate has a good gloss and beautiful appearance; compared with 304 stainless steel, the price is higher. 316 stainless steel plate has the following uses: equipment used in seawater, chemical, dye, papermaking, oxalic acid, fertilizer, and other production equipment; photography, food industry, coastal area facilities, ropes, CD rods, bolts, and nuts. You can buy 316 stainless steel plates according to your needs.

The use of 316 stainless steel plates has become more widespread with the development of the economy. People are closely related to stainless steel in their daily lives, but many people do not know much about the performance of stainless steel, and even less about the maintenance of 316 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 is a more stable oxide in nature. That is to say, although stainless steel is oxidized according to different conditions of use, it is eventually oxidized. This phenomenon is usually called corrosion. Electrochemical or chemical reactions occur on all metal surfaces exposed to the corrosive environment, and they are evenly corroded.

The parts with weak corrosion resistance in the passivation film on the surface of 316 stainless steel plate form a pitting reaction due to a self-excited reaction, forming small holes, coupled with the proximity of chloride ions, forming a strong corrosive solution, which accelerates the corrosion reaction speed. There are also intergranular corrosion cracks inside the stainless steel, all of which have a destructive effect on the passivation film on the surface of the stainless steel plate. Therefore, regular cleaning and maintenance must be carried out on the stainless steel surface to maintain its gorgeous surface and prolong its service life.
