Additional Finishing Services

Classic Electropolishing also offers a host of other finishing services as add-ons to the electropolishing process or as standalone services depending on your needs. These services include pickling, passivation, ultrasonic cleaning and material rinsing. In addition we work with a close group of vendors that offer finishing services if we aren't able to complete your entire order in house.

Material Handling

One of our core differentiation points is how we handle materials for our customers. Part of the electropolishing process includes unpacking your materials, racking them up, electropolishing them and shipping them back to you. Typically passivation and electropolishing is at the end of the manufacturing process. Any errors that occur once we receive your materials can be very costly. You can trust that we treat your components and work pieces with a high level of care throughout the manufacturing process.

Ask Us A Question

Feel free to reach out anytime to talk about anything metal finishing related. We are happy to help you solve complex manufacturing challenges. Classic was spun out of an existing manufacturer and we understand both metal machining and finishing processes. Over the last 20 years, we have helped numerous manufacturers solve complex design and engineering issues. We adhere to electropolishing ASTM standard B912, Passivation of Stainless Steels Using Electropolishing, ASTM A380 is the Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems. We enjoy speaking with customers throughout the finishing process to ensure your needs are being met.

What is Electropolishing?

Stainless steel has a protective oxide layer on the surface which helps protect it from corrosion. During the manufacturing process this protective layer can be removed. Electropolishing helps protect stainless steel from corrosion. Electropolishing is a subtractive process, material is removed from the metal in electrolytic solution when electricity is sent through the metal. Comparatively electroplating is an additive process, wherein material is added to your work piece through the process. In electropolishing, the material removed tends to be in the peaks and valleys of the surface of the metal. The remaining material tends to be smoother and shinier than the original material. Additional information about electropolishing can be found on Wikipedia.

Types of Electropolished Materials

The most typical type of material to be electropolished is stainless steel (304, 316, 400 series). One of the main reasons stainless steel is so prevalent is the cost point of electropolishing. Typically stainless steel products tend to be higher priced than products made of other materials. The added cost of electropolishing is absorbed in these higher prices. Products made of steel don't have this luxury although steel products can also be electropolished. We also electropolish nitinol, chrome, 17-4, mp35n, titanium, copper and brass. If you have a material that you would like electropolished don't hesitate to reach out and see if we can help.
