Shaw Stainless offers chemical and electrochemical treatments of stainless steel and other corrosion-resistant alloys. Electropolishing, also known as electrochemical polishing or electrolytic polishing, provides a smooth and shiny finish to your product.
Stainless steel has a protective oxide layer on the surface which provides corrosion-resistance. During the manufacturing or machining process, this layer may be removed. Electropolishing restores the corrosion-resistant properties often required in many highly-corrosive environments.
Passivating stainless steel is a process that is performed on the surface of a stainless steel or alloy component. In passivation, the stainless steel spontaneously forms a surface film which makes it more passive or a chemically inactive surface and is non-reactive to air. A low corrosion rate of the metal, stainless, or alloy is the desired result of the passivation process. ASTM B912 is the standard specification for passivation of stainless steels using electropolishing. ASTM A380 / A380M-13 is the standard specification for cleaning.
