Smart Ideas: Polishing Revisited
How to Get High Grade Stainless Steel: Electropolishing
Stainles steel is used in so many items we use daily. 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 involves the removal of iron particles from the steel surface by use of electrochemistry and electrolysis. This is how you shall know you have gotten rid of all the tiny corrosive metals from the surface. The corrosive particles like the iron bits are the remains from the manufacturing process. If not removed, the steel shall become corrosive fast. It shall thus be a less durable and poor quality to invest in. The only steel worth buying is one that has undergone electropolishing process.
There is also the fact that you shall end up with a more reflective and brighter looking piece of steel. You shall thus end up with a more durable metal that looks the part for longer. It shall also be easier to clean it. Dealing with rust on a metal has never been an easy task. Since the surface is smooth, it shall be much easier to clean. This is a much needed solution when it comes to items used for food, beverage, medical and chemical processes.
IT is also a much kinder process on the metal surface than other processes. Heat treatments and decarburization may have positive effects, but they also introduce stress and mess up the layers of the metal. It is also not thorough to use these processes when the design of the metal item is a complex one. There is likelihood of missing the curves, edges and crevices in the unusual shapes. You can count on electropolishing to hit all the surfaces.
You will also end up with a uniform and quick process to use. Since it shall be a fast and uniform process, the operational costs shall also be lowered. The need for more labor is eliminated, which adds to the savings. It is thus the choice process in large-scale stainless steel processing.
This is a process that yields great results only when there is adequate tools and competent personnel in charge. You cannot run the risk of using substandard processes, as the produced metal will be the same. Your steel will come off with irregular patterns, pitted and pebbly surfaces, as well as streaks and stains. You instead will know it was a good process when see no grain boundaries whatsoever when you view the surface under high magnification.
