characteristic:
316 stainless steel plate characteristics: due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance, and high-temperature strength are particularly good, and can be used under harsh conditions; excellent work hardening (non-magnetic); excellent high-temperature strength; solid solution state without Magnetic; cold-rolled products have the good gloss and beautiful appearance; compared with 304 stainless steel, the price is higher.
use:
Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer, and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, and nuts.
the difference:
The use of 316 stainless steel plates has become more extensive with the development of the economy. People are closely related to stainless steel in their daily life, but many people do not know much about the performance of stainless steel, and they know less about the maintenance 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 is formed on the surface, which exists in the form of a more stable oxide in nature. That is to say, although stainless steel has different degrees of oxidation according to different conditions of use, it is eventually oxidized, which is usually called corrosion. All metal surfaces exposed to a corrosive environment undergo electrochemical or chemical reactions and are uniformly corroded.
The parts with weak corrosion resistance in the passivation film on the surface of 316 stainless steel plate form a pitting corrosion reaction due to a self-excited reaction, forming small holes, coupled with the proximity of chloride ions, forming a strong corrosive solution, accelerating the corrosion reaction. speed. There is also intergranular corrosion cracking inside the stainless steel, all of which destroy the passive film on the surface of the stainless steel plate. Therefore, the 316 stainless steel plate surface must be regularly cleaned and maintained to maintain its gorgeous surface and prolong its service life.
