Why rack rust

Some customers say, my cabinet rusted, cabinet why rust, several reasons causing rust:
surface contamination, as on the surface of the workpiece, oil, dirt, acid, alkali and salt under certain conditions for the corrosive medium, react with cabinet to some of the stainless steel pieces, produce chemical corrosion lead to rust.
surface scratches: rack scratch damage to the passivation membrane, lower the cabinet stainless steel protection ability, easy to react and chemicals, chemical reactions and rust.
cleaning: cleaning not clean after pickling passivation can cause industry, direct corrosion cabinet stainless steel parts.
cutting: cutting slag, spatter is easy to rust material such as adhesion and corrosion medium to form a galvanic cell, resulting in electrochemical corrosion.
welding, welding area of the chemical and physical defects defects and form a galvanic corrosion medium, resulting in electrochemical corrosion.
material: stainless steel material chemical defects and surface physical defects to cabinet and form a galvanic corrosion medium, resulting in electrochemical corrosion.
passivation: pickling passivation effect is not good cause uneven or thin stainless steel surface passivation membrane, easy to form the electrochemical corrosion.
