Stainless Steel Finishing Techniques: Should You Choose Electropolishing or Passivation?
The processes of cutting, bending, machining, and polishing stainless steel during fabrication usually leave iron, silica, and other abrasive particles embedded within the surface of the metal. Finishing helps in removing these surface impurities, strengthening the properties of the metal, and improving its appearance. Electropolishing and passivation are two common techniques used in finishing stainless steel metal. Both of these techniques are distinct regarding the processes involved and outcome. It is essential to understand their characteristics and differences so you can choose the ideal one for your application.
