Electropolishing
Electropolishing is an electrochemical process similar to, but the reverse of, electroplating. The electropolishing process smooths and streamlines the microscopic surface of a metal object. As a result, the surface of the metal is microscopically featureless, with not even the smallest speck of a torn surface remaining.Learn about Electropolishing
Metal Pickling
Chemical Pickling (Chemical Descaling) is typically used to remove oxide layers resulting from welding, heat-treating, and other high temperature operations. All of these oxide layers are generally referred to as "scale" and must be removed prior to Electropolishing or Passivating. Pickling is sometimes referred to as "Acid Washing" or "White Acid Pickling".Learn about Metal Pickling
Passivating
Passivation is the chemical treatment of a stainless steel surface with a mild oxidant such as a nitric acid or citric acid solution. This is typically done to remove any "free-iron" from the surface of the metal, which enhances the corrosion resistance of the stainless steel surface and accelerates the re-formation of the passive layer.Learn about Passivating
Mechanical Polishing
Mechanical polishing covers grinding, polishing and buffing - all processes for improving the surface conditions of a product for decorative or functional purposes.Learn about Mechanical Polishing
