How to extend the life of 316 stainless steel angle bar?

How to extend the life of 316 stainless steel angle bar? People in their daily lives and is closely related to stainless steel, stainless steel angle bar are a lot of people think that will never rust, in fact, good corrosion resistance of stainless steel. The reason is that a passive film formed on the surface, it is a more stable form of oxides exist in nature. But many people recognize the performance of small stainless steel, 316 stainless steel angle bar maintenance will know more and less. That is, by the use of stainless steel, although conditions are different, not the same degree of oxidation, but in the end is oxidized, a phenomenon commonly referred to as corrosion. Exposed to the corrosive environment of the entire metal surface electrochemical reactions occur or the chemical reaction, uniform corrosion. 316 stainless steel angle bar surface passivation film corrosion resistance among the weak parts, due to the self-excited reaction to form pitting reaction of holes, coupled with chloride ions close to the formation of highly corrosive solution, to accelerate the corrosion reaction speed. There are between stainless steel internal corrosion cracking, all of these, the passivation film on the surface of the stainless steel plate occur damaging. Therefore, the stainless steel surface cleaning and maintenance must be carried out regularly in order to maintain its gorgeous surface and prolong life.
