Bellows Corrosion

After the reaction, the formed metal and atmospheric oxygen in the surface oxide film. Oxides of iron oxide formed on carbon steel, corrosion continues to expand, and ultimately the formation of holes. You can use paint or oxidation-resistant metal (eg, zinc, nickel, and chromium) plating to ensure the surface of carbon steel, however, as people know, this protection is only a film. If the protective layer is damaged, the following corrosion of the steel.hydraulic hose fitting
Varies depending on the amount of chromium, stainless steel hose corrosion resistance, resistance to atmospheric corrosion of steel, can significantly increase the added amount of chromium 10.5%, but the chromium content is higher, but still improve the corrosion resistance, but is not obvious. The reason is that the chromium steel alloy changes are similar to the type of surface oxide is formed on the metal oxides on the surface of the pure chromium. The chromium-rich oxide protect the surface adhesion, and to prevent further oxidation. Thin oxide layer, through which you can see the surface of stainless steel, stainless steel has a unique natural luster of the surface. In addition, if the damage to the surface of the exposed steel surface and atmospheric reactions self-healing, re-formation of this kind of "passive film" continue to play a protective role.hydraulic hose assemblies
