The hose hydraulic manifold block anti-corrosion technology

After the reaction was carried out within the metal tube under the pressure of the hydraulic manifold block and atmospheric oxygen, the formation of an oxide film formed on the surface. Iron oxide formed in the oxidation of carbon steel, corrosion continues to expand, and ultimately the formation of holes. To make or oxidation-resistant metal (for example, zinc, nickel and chromium) coating, to ensure that the surface of the steel, however, as people know, this protection is just a movie. When the protective layer is damaged, the following steel hydraulic testing machine
corrosion. The corrosion resistance of the stainless steel tube, according to the type of content, chromium, can significantly increase the atmospheric corrosion of steel, if the added amount of chromium 10.5%, but the chromium content is higher, despite the improvement of the corrosion resistance, but it is not very obvious. Chromium steel alloy changes will be very similar to the type of pure chromium oxide surface oxides formed on the metal surface. Solid adhesion of the chromium-rich oxide protective surface to prevent further oxidation. This thin oxide layer, through which you can see the natural luster of the stainless steel surface. Stainless steel has a unique surface and, if the damage to the surface of the steel surface and atmospheric reaction self-healing exposed to further the formation of the passivation film, to play a protective role.
Hose anti-corrosion technology, we have a new understanding of the hose anti-corrosion treatment, increased production costs and customers can reduce tube life.metric hydraulic fittings
