Help on passivation system


I am looking to bring passivation of 430F material in house, and am looking for some useful guidelines, and starting a system.

As you already know, 430F can be a bit tricky because of the high sulfur. But you can do it okay if you use the right procedures. We recommend soaking first in 5% NaOH to remove the sulfur from the surface, then passivate with our citric acid formulations. You can also use nitric acid if you want to deal with the hazards. See our Web Page for details and give us a call for assistance. if you need it.

There is a non-nitric, non-citric, electro-passivation process available that offers maximum performance without any environmental or worker safety issues. Please see our website or contact me for more info.
