Profile: Hard Chrome Specialists, Inc. offers chrome & electroless nickel plating and electropolishing products. We are an ISO 9001:2008 certified company. Our industrial passivation involves cleaning the surface of steel components to remove all particles and contamination. Depending on the nature of materials, we will choose the best etching solution (typically citric acid). This acid dissolves all non-passive particles and disparities on the surface of the component materials or parts and renders them less susceptible to corrosion. Electropolishing uses an electrical current to remove ions and therefore material from the desired parts.
