The Electropolishing Process
There are many things which are manufactured using stainless steel metal. 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. These things are best made using stainless steel that has gone through the electropolishing process.
There are other methods available for polishing the steel surfaces, but none of them can give off the same effect as this one. This is what makes electropolishing so much better. It is what results in the removal of iron and other corrosive particles from the steel surface, when electrochemistry and electrolysis is introduced. 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. You should only invest in steel that had electropolishing done on it.
You shall also get a brighter and more reflective surface on steel. You shall thus end up with a more durable metal that looks the part for longer. You will find cleaning it much easier. 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. This benefit is especially important in items used for food, beverage, medical and chemical processes.
This is also hoe you treat the metal to a much gentler process. Processes such as heat treatment and decarburization are good, but turn bad when they give off too much stress and spoil the layers of the metal. 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. You can count on electropolishing to hit all the surfaces.
You will also end up with a uniform and quick process to use. This will in tum make it a more affordable process to adopt. There is less need for more labor, and more savings to be made. It makes sense to go for this 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. If you go for anything less, you will end up with a poorly polished batch that shall not serve its purpose well. The metal shall have 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.
