passivation of SS sheet
passivation of SS sheet
(OP)
Hi all,
You normally use nitric acid or citric acid to passivate stainless steel. BUT, I was told that you can also use Vinegar.
Is this true? If so, how it's done?
Thanks a lot

RE: passivation of SS sheet
There are many options listed. Why wouldn't you use one of them?
You need to use an oxidizing acidic solution to passivate. You are trying to dissolve free iron from the surface. Assisting formation of a uniform and robust chrome oxide passive surface film is a secondary issue. I could do that with hydrogen peroxide, but it wouldn't remove any iron.
