Description

The citric acid works by creating complex molecules that bind up many metallic ions that would have the effect of reducing the corrosion resistance of the stainless steel. These complex molecules are typically water soluble in the aqueous solution in which the citric acid is dissolved and they will not redeposit metal ions as mineral acids are known to do. The citric acid also works to enrich the chromium concentration at the surface of the metal.

The citric acid passivation process is used very successfully in the pharmaceutical, medical and semiconductor industries, and produces superior results to the use of nitric acid alone, which has continued in use for historical reasons. Current studies of the surface chemistry of stainless steel shows that citric acid passivation eliminates the contaminants from the surface more completely and helps to produce a truly passive surface by giving the best chromium enrichment to the surface.

Electro-Max, Inc specializes in the finishing of stainless steel through a process called Electropolishing and passivation. Our goal is to become your only source for metal finishing by providing superior customer interaction, excellent value, and top-notch quality.
