Stainless steel, stainless steel mesh material in layman's terms, is not easy to rusty steel. Part actually have both stainless stainless steel, acid (corrosion resistance). The corrosion resistance of stainless steel is due to its rich chromium oxide film on the surface (passivation film) form, but in fact, the stainless steel will rust? The answer is: yes. The corrosion resistance of stainless steel is relative, experiments show that the steel in the atmosphere, the weak medium such as water and corrosion resistance in nitric acid oxidation, such as the medium is not the same. Many stainless steel and metal, or contact with the hand when the air is affected by the environment will also be to oxidize, in addition, the stainless steel surface after machining, such as: welding, stamping, curl, such as heat treatment process, generate a layer of black oxidation of hardening layer, and also formed many visible or invisible to the naked eye small burrs and acute Angle burrs, etc., in general, used a mechanical method is difficult to remove them, influence the full play of the workpiece material itself characteristic, in order to solve these problems, people use a lot of ways to prevent rusting of steel and have a rusty steel to remove rust stains, but relatively than rust removal to prevent steel rust stains are much more meaningful.
