Stainless steel is really not rust? Why rust?

The cause of the stainless steel will rust: stainless steel is the most easy to misleading its name: stainless steel. When the stainless steel in mechanical processing, assembly, welding, weld detection brought to surface oil pollution in the process, such as the material damage the surface of the oxide film, reduces the corrosion resistance of stainless steel, stainless steel, corrosion will occur and the resulting other forms of corrosion. So it is necessary to other appropriate antirust processing, to improve its corrosion resistance, it has been proved that only finally after passivation of stainless steel, to keep the surface passivation treatment for a long time, in order to keep the surface of the passivity of stable for a long time, thus to improve corrosion resistance.
