Importance of the Electropolishing Process
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 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. 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. This is why you need to buy the ones that have undergone electropolishing.
This process also makes for a brighter and more reflective surface on steel. This shall be a shine that shall last for long time to come. It shall also be easier to clean. Dealing with rust on a metal has never been an easy task. The smooth surface as a result of electropolishing makes for a much easier to clean surface. This is a much needed solution when it comes to items used for food, beverage, medical and chemical processes.
This is also hoe you treat the metal to a much gentler process. Heat treatments and decarburization may have positive effects, but they also introduce stress and mess up the layers of the metal. If the metal is in a complex design, using mechanical polishing on it shall be a hard task. There is likelihood of missing the curves, edges and crevices in the unusual shapes. You can count on electropolishing to hit all the surfaces.
It also happens to be a uniform and fast way of doing this kind of work. 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 makes sense to go for this process in large-scale stainless steel processing.
The process works best when there are adequate conditions in place, and highly trained staff handling it. Anything less runs the risk of giving off a poorly polished batch, which cannot be as reliable and durable as expected. 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.
