Re: [MW:32307] Is there any difference in performance betweenpickling and passivation?

Pickling is a matal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust contamination or scale 

 A solution called pickle liquor, k2 chemical paste which is usually contains nitric acid, is used to remove the surface impurities. It is commonly used to descale or clean steel in various  processes.

Passivation

Passivation is a chemical treatment for ss and other alloys that enhances the ability of the treated surfaces to resist corrosion

Passivation removes surface contamination

Passivation increase corrosion resistance

Passivation reduces the risk of product Contamination

Passivation allows you to extend system maintenance intervals
