What Is SS Electropolish Services?
SS Electropolish Services is an electrochemical process opp. to electroplating used machinery are same. The Electropolish process smooth and streamlines the microscopic surface of a metal object. As result the surface of the metal is microscopically featureless. Electropolish will remove hydrogen from the surface of the part making it difficult for bacteria to grow. Electropolish is often referred to as a “reverse plating” process. electrochemical in nature, Electropolish uses a combination of rectified current and a blended chemical electrolyte bath to remove flaws from the surface of a Metal Part.
There are two types of Electropolish facility.
Standard : ASTM A554, A312, A778, JIS G3446, CNS G3119, GB
Dimensions : ASTM, ASME and API
The Electropolish Process:
Electropolish is widely used in the Industrial, Medical and Sensor Markets.
Electropolish involves passage of electric current through a workpiece, while it is submerged in a specially-designed acid solution. The process is essentially the reverse of electroplating, in that the surface of the workpiece is actually “stripped away.” When used on stainless steel, the process removes iron and nickel (as well as non metallics) from the surface, thus enhancing the chromium content and corrosion resistance of the workpiece surface. The amount of surface material removed can be precisely controlled by voltage, current, time and temperature. Electropolish also has the added benefit of attacking the “high points” of the surface of the workpiece more aggressively, resulting in a smoothing, or polishing of the surface. In many cases such as medical, food and beverage, and semiconductor products, this smoothing of the surface reduces the microscopic crevices in which bacteria can propagate and tiny particles can accumulate, thus aiding sterilization and cleaning processes.The removal of metallic and non-metallic particles, that are often added to the surface by cutting and forming processes, also results in a superior surface for welding. This reduction of impurities reduces he presence of crack forming inclusions that can compromise weld strength
The diagram below shows a typical Electropolish process. The workpiece is mounted on special racks of either copper or titanium. The rack, along with the workpiece, is submerged into an acid solution (held at a specific temperature), and current is passed from the anode (workpiece), through the acid solution, and into the cathode (lead). The surface of the workpiece is literally “dissolved” away, leaving an extremely clean and polished surface on the workpiece.
Electropolishing stainless steel is a “reverse plating” process that uses an electrochemical solution to remove the outer skin of a metal part. … Electropolishing stainless steel significantly, especially 300 and 400 series stainless steel, improves a part’s corrosion resistance, leaving it with a lasting bright finish.
Benefits SS Electropolishing Services
Polishes areas inaccessible by other polishing methods
Improves the surface finish by leveling micro peaks and valleys
Removes a small amount of material (roughly 20-40 micrometers thick) from the part surface, taking small burrs and high spots with it
Provides a corrosion resistant surface
Creates a bright, reflective finish
Improves surface reflectivity and brightness
Removes iron from the surface and enhances the chromium/nickel content, providing the best method of passivation for stainless steel
Can be used to slightly reduce the size of parts, if necessary
Provides a clean and smooth surface that is easier to sterilize
Removes surface discoloration caused by heat treating and/or oxidation
Most Frequently Asked Questions
Electropolishing is good for creating a surface that is cleaner, smoother, and more representative of the base metal than any other method currently in use. This lends itself to bio-pharmaceutical applications where vessels and equipment must be easily verified as being clean. Electropolishing also reduces surface area (vacuum applications), passivates the surface to a degree, and removes any imbedded impurities that may be present following mechanical polishing.
An electropolished surface is only as durable as the base metal itself. Rough handling and chloride damage are the two principle types of damage we repair most often.
Electropolishing removes material while electroplating deposits material. The two processes are very similar in that both use electrolytes to carry an electrical current, but with different polarity.

It is often described as the reverse of electroplating. It differs from anodizing in that the purpose of anodizing is to grow a thick, protective oxide layer on the surface of a material rather than polish. Electropolishing is commonly used on stainless steel components after they have been sharpened.
