When the addition amount reaches, the corrosion resistance of steel can still be improved, but it is not obvious
The reason is that when alloying steel with chromium, the type of surface oxide is changed to be similar to that formed on pure chromium metal
This tightly adhered chromium rich oxide protects the surface from further oxidation
This oxide layer is thin, through which you can see the natural luster of the steel surface, so that the stainless steel has a surface
Moreover, if the surface layer is damaged, the exposed steel surface will re form this oxide & quot; Passive film;, Continue to play a protective role

Structure: it is welded as a whole, with a cleaner's tool cabinet office, built-in hook, ventilation design, school class cleaning tool cabinet, and a drainage drawer at the bottom
