Producers Share And Decipher The Motives Why Pu Steel Twine Telescopic Hoses Are Corroded

Many customers reflect that the pu steel wire expansion hose bought back is corroded, what is the reason for this? Let for you to explain!

The pu steel wire telescopic hose is made of steel wire, once the steel wire disclosure, it is quickly oxidized by the air, so that the corrosion continues to expand, and eventually form holes. So, is there a way to make pu steel wire telescopic hose is not corroded? We can utilize paint or oxidation-resistant metal for plating to ensure the carbon steel surface, but, as people know, this protection is only a film. If the protective layer is destroyed, the steel underneath will begin to rust.

In fact, the corrosion of pu steel wire expansion hose is mainly due to the content of chromium within the steel wire, the higher the content of chromium the greater its corrosiveness! pu steel wire expansion hose of this oxidized layer is thin, through which you can see the natural luster of the stainless steel surface, so that stainless steel has a unique surface. Moreover, if the surface layer is damaged, the exposed steel surface will react with the atmosphere for self-repair, re-form this "passivation film", continue to play a protective role.
