photo_electropolishingStainless steel electropolishing

Electropolishing, often called reverse plating, is an electrochemical process used extensively in the medical field. The process removes iron and other metallics from the surface of stainless steel leaving a bright, burr free surface. Whether your goal is aesthetic improvement, passivation and corrosion resistance, or reduced surface resistance, Brainin’s stainless steel electropolishing team routinely surpasses client expectations.
