I am told that in order to passivate stainless steel, I'll need a strong concentration of Citric acid, and NaOH.
Well I got both of these from work.
I was wondering if anybody here has been able to passivate stainless steel components on their own. If so, was it a success? My stainless steel tubes are going to be in a potentially corrosive environment 24/7, so I want the best very best.
