Small Passivation Operation Start-up
Currently we outsource parts made of 303 Stainless Steel to be passivated. We would like to bring this in house as a small operation, but do not know where to get started. What chemicals, requirements, and processes are required? Any information you could provide would be wonderful.

The basic equipment and chemicals is a very minor part of the total question. Safety, Haz Waste disposal, ventilation, quality control measures, corrosion proofing and permitting are far more significant questions. I am a very affordable consultant and would be happy to assist you in taking a good look at the whole problem of bringing this "in house".

Kelly,
Look in QQ-P-35C (canceled) [link is to free spec at Defense Logistics Agency, dla.mil]. We recently started a passivation process in house for what sounds like just the same reasons you are.

Kelly:
You can do it very easily and economically using safe and environmentally friendly chemistry based on citric acid. Please contact us and we will tell you how to set it up.
