Passivation improves the corrosion resistance of stainless steel. Surface contaminations, including grease, dirt, and iron may disrupt the formation of stainless steels' naturally corrosion resistant surface layer.

During a chemical passivation treatment, the surface of a part is chemically treated by a mild oxidant. The process removes free iron and other foreign contaminants and promote the formation of a chromium rich corrosion resistant layer if required.

Florida Anodizing has performed passivation treatments with excellent results for over 7 years. We have the capacity to passivate stainless steel components of various sizes. Florida Anodizing will perform chemical passivation treatments in compliance with ASTM-A-967, QQ-P-35, AMS QQ-P-35 and AMS 2700 specifications, or your industry standards. Type II (medium temperature nitric acid with sodium dichromate) and Type VI (low temperature nitric acid) are offered.

This is an example of Passivation.
