Video introduces a new concept in protection for stainless steel appliances and more. The video includes installation and scratch removal instructions. Check Laser-Cutting Surface-Protection Film. Often used to protect sheet metal during fiber and CO2 laser cutting, this film is also good for other fabrication processes such as bending, stamping, and forming. You can even leave this film on finished parts for protection against damage during shipping and storage. Causes of Corrosion. Stainless steel's corrosion resistance is due to a thin, chromium-rich, transparent oxide film on the surface 1.This protective film develops when more than 10.5 percent of chromium is present in the alloy and when the gas or liquid environment the stainless steel is exposed to provides oxygen to its surface. Heat is the safest way. Apply for a few seconds (or minute, then pull until it's not easy to pull. Repeat. Use gloves if too hot. Chemicals and application products, such as certain cloths, can damage stainless steel and/or other metals. You could heavily damage the finish, even if you are safe.

Again, be sure to rub in the direction of the grain. A piece of wet fine-grit sandpaper can also be used to remove deeper scratches. Always keep it wet, and follow up with The chemistry which is used to strip the CrN or chromium is as follows: Take step 1) 1 lit of DI water heat up to 50 °C. Then take step 2) 15 gms of KMnO4 and 40 gms of KOH. mix step 2) in step 1) then insert the tools which has to be stripped. Heat the solution up to 90 ° C. Here your stripping time will take 4-5 hrs.

Submerge the chrome-plated object in the solution until chrome strips off. Wash the object thoroughly in soap and water, and rinse before drying. 2. Use sodium hydroxide (lye) to strip chrome from ferrous metals and carbon steel. MHDT6G.
