Passivation of 304L stainless tank in the field. [Texas] 

May 8, 2008

I want to test and passivate a 304L tank in the field and have been told that I can hydro and passivate at the same time using 3% nitric acid. I'm confused at this point and want to make sure it's done right before putting into service. Any help would be appreciated.
