Stainless steel buckles will also rust? I believe many friends will not believe this problem. Everyone will think that "stainless steel buckles are not rusty, and rust is not stainless steel. Maybe there is something wrong with the buckle steel"

In fact, the stainless steel hinge is based on an extremely thin, strong, dense and stable chromium-rich oxide film formed on its surface to prevent the infiltration and oxygenation of oxygen atoms from continuing to obtain the ability to resist rust.

But if for some reason this film is continuously destroyed, oxygen atoms in the air or liquid will continue to infiltrate or iron atoms in the metal will continue to separate out, forming loose iron oxide, and the metal surface will be constantly rusted.
