Manufacturers Share The Reason Why The Steel Wire Expansion Hose They Bought Is Corroded

Many customers report that the steel wire expansion hose they bought is corroded. What is the reason? Let me explain it to you

The steel wire exists in the steel wire expansion pipe. Once the steel wire is exposed, it is quickly oxidised by the air, causing the corrosion to expand and eventually form holes. So, is there a way to prevent steel expansion tubes from corroding? We can use paint or antioxidant metal for plating to ensure the surface of carbon steel, but as we all know, this kind of protection is just a film. If the protective layer is destroyed, the steel underneath will start to rust.

In fact, the corrosion of steel wire expansion tubing is mainly due to the chromium content in the steel wire. The higher the chromium content, the more corrosive it is! The oxide layer of this steel expansion pipe is thin, and the natural luster of the stainless steel surface can be seen through the oxide layer, giving the stainless steel 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.
