Characteristics: due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high-temperature strength are particularly good. It can be used under harsh conditions. It has excellent work hardening (non-magnetic), excellent high-temperature strength, non-magnetic in solid solution state, good gloss and beautiful appearance of cold-rolled products. Compared with 304 stainless steel, the price is higher.
Uses: seawater equipment, chemical, dye, paper making, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.

Maintenance and service
The use of 316 stainless steel sheet, becomes more and more extensive with the development of economy. People are closely related to stainless steel in their daily life, but many people don't know much about the performance of stainless steel, and they know less about the maintenance of 316 stainless steel plate. Many people think that stainless steel will never rust. In fact, stainless steel has good corrosion resistance. The reason is that a passive film is formed on the surface, which exists in the form of more stable oxide in nature. In other words, although the oxidation degree of stainless steel is different according to different service conditions, it is finally oxidized. This phenomenon is usually called corrosion. All metal surfaces exposed in corrosive environment undergo electrochemical reaction or chemical reaction, and are uniformly corroded.
In the passive film on the surface of 316 stainless steel plate, the parts with weak corrosion resistance form pitting reaction and small holes due to self-excited reaction. In addition, chloride ions are close to each other to form a strong corrosive solution and accelerate the speed of corrosion reaction. There are also intergranular corrosion cracking in stainless steel, all of which destroy the passive film on the surface of stainless steel plate. Therefore, the stainless steel surface must be cleaned and maintained regularly to maintain its gorgeous surface and prolong its service life.
