The Electropolishing Process
There are many areas in life where we need rust and stain-free finished steel. You shall see its use in items like washing machine drums, surgical devices, knives, and any other item which should not deform, corrode or have minute tears in the course of its operation. Electropolishing is the process of smoothing and streamlining the metal surface.
There are other methods available for polishing the steel surfaces, but none of them can give off the same effect as this one. This explains the preference for electropolishing. It is the elimination of iron particles and other corrosive material from the steel surface when electrochemistry and electrolysis is applied. This process assures you of the complete removal of the tiny bits of corrosive metals from the surface. These corrosive particles, such as iron bits, are usually left behind from the manufacturing processes. If not removed, the steel shall become corrosive fast. This is how you find some pieces of steel rusting away. This is why you need to buy the ones that have undergone electropolishing.
There is also the fact that you shall end up with a more reflective and brighter looking piece of steel. This shall be a shine that shall last for long time to come. It shall also be easier to clean it. Dealing with rust on a metal has never been an easy task. The smoothness realized after electropolishing will pull in less contaminants, which make for a faster and less strenuous cleaning experience. Such a feature is highly sought after in items used for food, beverage, medical and chemical processes.
This is also hoe you treat the metal to a much gentler process. Processes like heat treatment and decarburization may get rid of the bits, but they shall also stress the metal unnecessarily. If the metal is in a complex design, using mechanical polishing on it shall be a hard task. They shall definitely miss the curves, edges and crevices in it. ELectropolishing does away with such fears, since it covers all surfaces.
It also happens to be a uniform and fast way of doing this kind of work. This will in tum make it a more affordable process to adopt. This leads to huge savings as the labor costs are slashed. It is thus the choice process in large-scale stainless steel processing.
You shall realize the best results when there is adequate process controls and highly skilled and well educated professionals in charge. If you go for anything less, you will end up with a poorly polished batch that shall not serve its purpose well. Your steel will come off with irregular patterns, pitted and pebbly surfaces, as well as streaks and stains. You should see no grain boundaries whatsoever when you view the surface under high magnification.
