Overview of the hose

Hose mainly divided into: stainless steel hose, metal hose, corrugated hose, plastic hoseCorrosion resistance of stainless steel hose depends on the chromium content, if the amount of chromium added to 10.5%, the atmospheric corrosion resistance of steel significantly increased, but the higher chromium content, while still being improved corrosion resistance, but obvious. The reason is of steel with a chromium alloying Hydraulic tube fittings, the change in the type of surface oxide became similar to pure chromium metal oxide formed on the surface.This tight adhesion of chromium-rich oxide protective surface to prevent further oxidation of this thin oxide layer, through which you can see the surface of the natural luster of stainless steel, the stainless steel has a unique surface. Moreover, if the surface is damaged, the exposed steel surface and atmospheric reactions will self repair, re-formation of this kind of "passive film" and continue to play a protective role.
