Webit could be time to passivate. 1. Citric acid is also sometimes used for passivating stainless steel. It is an acid that can effectively remove iron and its compounds from surfaces. … Web20 Apr 2004 · To develop an alternative passivation procedure for SS303, citric and phosphoric acids have been evaluated. The experimental results show neither acid causes a significant amount of sulfur deposit. Thus, these two acids can be used as alternatives to nitric acid passivation for NIF applications.
WebFixing this condition calls for re-passivation. Passivating stainless steel is typically accomplished in industry by dipping the part in a bath of nitric acid. Nitric acid dissolves any free iron or other contaminants from the surface, which cleans the metal, and it re-oxidizes the chromium; all in about 20 minutes. But you don't need a nitric ... Web16 Sep 2013 · DoD and NASA agreed to collaborate to validate citric acid as an acceptable passivating agent for stainless steel. This paper details our investigation of prior work …
