Over 100 years of combined Electropolishing & Metal Finishing experience.
Electropolishing per ASTM B912 is an electrochemical process that effectively removes surface material and imperfections from metal objects. This process serves many purposes from cosmetic improvements to ultra clean surfaces.
Pickling per ASTM A380 is a cleaning process that involves the actual chemical de-scaling of the metal article. Ultimately, this process removes metallic and non-metallic contamination thereby improving the surface of the object.
Passivation per ASTM A380 and A967 of stainless steel allows for a more passive and corrosion resistant surface. This process is performed when contaminations such as free iron, oxide scale, rust, etc. are deposited on the surface.
