Mill scale WikipediaThe Whys and Hows of Hydrochloric Acid Pickling

Mill scale often shortened to just scale is the flaky surface of hot rolled steel consisting of the mixed iron oxides iron II oxide FeO iron III oxide Fe 2 O 3 and iron II III oxide Fe 3 O 4 magnetite Mill scale is formed on the outer surfaces of plates sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling millsHydrochloric acid dissolves scale rapidly so these accumulations do not occur Also at high temperatures in sulfuric acid ferrous sulphate monohydrate forms and settles out in the tanks due to decreasing solubility at higher temperatures this does not happen with hydrochloric ac Of course hydrochloric acid has its disadvantages too
