Passivation kits for stainless steel
I'm interested in finding a passivation product (preferably citric based and in paste form) to use for maintenance weld repairs of a sanitary (PW-100) Deionized Water system. We currently fabricate subcomponents and ship to passivation companies for a nitric passivation cycle. If we are passivating a large quantity we will mobilize a passivation contractor to our site for a citric based passivation. Our interest is in finding a "user friendly" product for emergency weld repairs which would provide the same end result as the aforementioned processes.Bobby Williamson

There are good citric acid based passivation gels available for this application from Stellar Solutions, Inc.
The citric products produce excellent passivation of welds compared to nitric. However, they will NOT remove all of the weld discoloration like a nitric/HF paste will. They do, however give you a safe, easy way to get good, passive welds. If you need aesthetic beauty, you need to brush the weld first with a good stainless steel wire brush, treat it with an electric wand or blast it with a good glass bead system. Let us know how we can help.
