Stainless steel is not only a building material, but also a good decorative material. So after a long time of research and accumulation, stainless steel whether steel plate, coil or  strip.

Their surfaces can be treated in such a way as polishing, sandblasting, wire drawing, high-gloss PVD, plating, ED, spraying, etching, laser.
The use of stainless steel with the development of economy has become more widely, people in daily life is closely related to stainless steel, but many people do not know much about the performance of stainless steel, the maintenance of stainless steel is less. Many people think that stainless steel is never rust, in fact, stainless steel corrosion resistance mechanism for the formation of a layer of passivation film on its surface, in nature it exists in the form of a more stable oxide, that is to say, although stainless steel according to the use of different conditions, the degree of evolution is not the same, but ultimately are oxidized. This phenomenon is often called corrosion.
The metal surface exposed in corrosive environment will be corroded by chemical reactions. Stainless steel surface passivation film in the corrosion resistance of the weak part, due to the self-excited reaction and the formation of corrosion reaction, the formation of small holes, coupled with chloride ions close to the formation of a strong corrosive solution, accelerate the speed of corrosion reaction. There are stainless steel internal crystal corrosion cracking, all these, the passivation film on the surface of stainless steel damage. Therefore, the stainless steel surface must be regularly cleaned and maintained in order to maintain its gorgeous surface and extend the service life. When cleaning the surface of stainless steel, we must pay attention not to scratch the surface, avoid the use of bleaching ingredients and abrasive detergent, steel wire balls, grinding tools, etc., in order to remove the washing liquid, wash the surface with clean water at the end of the washing.
Stainless steel surface dust and easy to remove dirt, available soap, weak detergent to wash; Binder ingredients, use exactly or organic solvents (ethanol, benzene) scrub.
Stainless steel surface grease, oil, lubricating oil pollution, wipe clean with a soft cloth, and then wash with neutral detergent or ammonia solution or with special detergent cleaning.
Stainless steel surface oil bleach and a variety of acid attachments, immediately wash with water, then use ammonia solution or neutral carbonic acid soda water solution immersion, with neutral detergent or warm water wash.
Stainless steel surface error caused by rust, can be 10% nitric acid or grinding detergent washing, can also be used to wash special washing drugs.
As long as we use the correct maintenance method, we can extend the service life of stainless steel, keep its crystal, bright, gorgeous style.
