Metals, including austenitic steels and alloys, have been extensively applied in industrial and engineering applications. Passive films on metal surfaces are very important for corrosion protection. However, localized attack, such as passive film breakdown and the initiation of pits, is found upon exposure of such metals to aggressive ion-containing environments, leading to material failure You may have to abrasively remove the clearcoat with the grain. (about the only thing good about doing it this way is you remove the scratches at the same time.) Once you got the clearcoat off you can use a sanding block with 120-220 grit sandpaper and SAND ONLY WITH THE GRAIN!. Secondly, when cleaning stainless steel, you should always go with the grain and never, ever, use a metal or harsh scouring pad. A soft, plastic, scrubber can sometimes be used when needed, but a good microfiber cloth * is always the best cleaning cloths for stainless steel. Also, avoid using products that contain chloride. Protective coating films should remain on stainless steels until it is essential to remove them for fabrication or installation purposes. This minimises the risk of damage to the stainless steel structure. Surface damage on stainless steels such as scratches and gouges can allow entrapment of contaminants, providing ideal locations for corrosion. Stainless steel sheet of 3 m/m without bending marks. In the 21st century, it is no longer necessary to say how important quality is in all the products that are manufactured today. And, as it could not be otherwise, also in the metal sheet bending phase the quality and absence of marks is not important, but essential.
