The aerospace, electronics, medical and similar high-tech industries have used chemical passivation for years, but are now using electropolishing of metals as a replacement process. The passivation methods of using citric or nitric acid solutions to remove surface contamination from stainless steel produce clean, corrosion resistant surfaces, but do not achieve the bright and lustrous appearance obtained with Electro-Kleen’s electropolishing methods. The corrosion resistance of electropolished stainless steel far exceeds that of standard passivation processes. For industries in which a fine metal finish is necessary, electropolishing brings quality to unprecedented levels at a comparatively low price. When mechanical polishing is too expensive or cannot accomplish what is required, call Electro-Kleen!
