AquaVantage® Passivation is a dilutable citric acid formulation specifically developed for the passivation of stainless steel parts. AquaVantage® Passivation conforms to multiple aerospace specifications and is specifically formulated for use in the Space, Aerospace, and Medical manufacturing industries.
This product has been designed to be used in conjunction with Brulin brand immersion or ultrasonic detergents.
AquaVantage® Passivation is suitable for use on a wide variety of alloys. Some selected categories of materials compatible with AquaVantage® Passivation include*:
Corrosion resistant steel alloys including: Austenitic • Ferritic • Free Machining • Precipitated Hardened • Martensitic grades. This includes typical grades of 303, 304, 308, 311, 316, 17-4, and 420, among others.
For complete list see table 4 in AMS 2700.
* Material compatibility should always be confirmed via testing with specific contaminants under specific cleaning conditions.
Thoroughly rinse parts immediately after removal from the passivation solution. Final rinse should be carried out in clean water.
Use of de-ionized water for the rinse is recommended.
Once passivating is finished, and the parts are rinsed and dried, they should be completely free of surface defects. Pitting, etching, hazing and staining would all be indicative of the possible presence of free iron. Post-passivation, parts can be tested for free iron as required by the specifications or purchaser to verify passivation success.
