* Wheathered steel has protection against atmospheric corrosion by oxidation of an outer layer, called patina.
George: Regarding applications, heavier gold is most often specified where there is a possibility of atmospheric corrosion.
A common type of gradual corrosion is oxidation, also known as atmospheric corrosion. Whenever a metal is exposed to a gas that contains oxygen atoms along with atmospheric moisture, a reaction occurs.

In the hydrodesulfurization process, these heat exchangers can suffer deterioration from atmospheric corrosion (externally, when the coating cannot completely protect the external surface) and by ammonium bisulfide corrosion (internally, when ammonium salts are formed) [5-7].
