Stainless steel, like many metals, is oxidized and rusts when it comes into contact with the air by hand or in contact with the environment. In other cases, the surface of the stainless steel workpiece is machined, for example: welding, stamping, zigzag, heat treatment and other processes, the formation of a black layer of oxidation and transformation hardening layer, together, they form many fine burrs that are visible or invisible to the naked eye, as well as sharp edges. In general, it is difficult to remove them mechanically, affecting the performance of its workpiece raw materials themselves, in order to deal with these problems, many methods have been used to prevent the rust of steel parts and rust of steel parts will be removed rust stains, but to prevent the rust of steel parts than rust stains to be much more meaningful. Warner world through small screen to remind you of stainless steel screen has a beautiful surface and corrosion function, do not have to go through the surface treatment, such as plating, so the appropriate use of a wide range, including the use of decorative hardware industry. Decorative stainless steel parts, such as handle, handle and other products are generally after the formation of the surface polishing treatment.
In addition to being very smooth, shiny and beautiful, the polished surface of the product will also greatly improve its anti-rust function, because in the process of polishing, the surface of the product was heated by high-speed conflicts, etc. , the surface of the product to form a layer of molecules placed relatively regular thin chromium film, this film separated from the invasion of oxygen and steel, play a role in corrosion resistance. Also often to its surface clean, prevent some such as perspiration, oil stains and acid-containing dust in the air and other corrosive substances attached to its surface, and then cause corrosion. During the cleaning process, remember not to use cleaning and scrubbing articles rich in acid and alkali, these substances can form oxidized rust through the fine (invisible) pores of the chromium film or directly with the steel in a small amount of other material other than chromium.
