Steel Pickling: The Essential Guide | MachineMfg

The iron oxide scale is dissolved by chemical reaction with acid (dissolution). Metal iron reacts with acid to generate hydrogen, and mechanically peels off the scale (mechanical peeling effect). Generated atomic hydrogen reduces iron oxides to ferrous oxides that are prone to acid action, and then removed by the action of acid (reduction).
