Most people subconsciously think that precision steel pipes will not rust because of their precision. To be honest, the corrosion resistance of precision steel pipe is very good, so its cost performance is relatively high, because his surface has a layer of transition film, which can reduce the possibility of oxidation.
However, due to people's excessive indulgence of precision steel pipes, they will not care about the maintenance of precision steel pipes. However, the part of the precision steel pipe that shows that the corrosion resistance of the film is relatively weak will form a point corrosion reaction due to the self-excited reaction, and the production of small holes will be accommodated into a strong corrosive solution with the close chloride ions, which will accelerate the corrosion speed. In addition, the intergranular corrosion cracking inside the stainless steel will destroy the transition film on the surface of the stainless steel plate. Therefore, the surface layer of the precision steel pipe should be cleaned and maintained at a certain level to better extend the service life of the precision steel pipe.
