Reasons for Corrosion Resistance of Stainless Steel Pipes

Nowadays, many people like to use stainless steel pipes in the whole process of applying pipelines. This is even more due to the corrosion resistance of stainless steel pipes. So what do you know about the corrosion resistance of stainless steel pipes? All metal materials react with the co2 in the air and produce an oxide film on the surface. The tragedy is that the iron oxide produced on ordinary carbon steel is oxidized again, which causes the rust to continue to develop and eventually produces holes. Can use paint Or oxidation-resistant metal materials (such as zinc, nickel and chromium) are electroplated to ensure the surface of carbon steel, but, as everyone knows, this type of maintenance is only a plastic film. If the thickness of the protective layer is reduced Destroyed, the steel underneath has just begun to rust.

 

The corrosion resistance of stainless steel industrial pipes lies in chromium, but because chromium is one of the components of steel, the maintenance methods are different.

 

When the amount of chromium added is 10.5%, the air corrosion resistance of the steel can be significantly improved, but when the chromium content is higher, although the corrosion resistance can still be improved, it is not significant. The reason is to use chromium to develop fine-grained steel. When strengthening the solution, change the type of surface oxides into surface oxides similar to those produced on pure chromium metal materials. This inseparable adherent chromium-rich oxide maintains the surface and avoids further oxidation. This type of oxide layer is extremely thin, Through it, the natural glossiness of the steel surface can be seen, so that the stainless steel industrial pipe has a distinctive surface. Moreover, if the surface is destroyed, the exposed steel surface will reflect the air and carry out its own maintenance.
