The surface of metal exposed to corrosive environment has electrochemical reaction or chemical reaction, which is uniformly corroded. The corrosion resistance of stainless steel door surface passivation film is weak. Because of self-excited reaction, pitting reaction is formed, forming small holes, plus chloride ions near, forming strong corrosive solution, accelerating corrosion reaction.  There are also intercrystalline corrosion cracking in the stainless steel, all of which have a destructive effect on the passivation film on the stainless steel surface.
