Pickling Steel

Low-temperature mill scale consists of two iron oxide layers and develops when steel is heated in an annealing or finishing procedure at less than 1070F Cracks in either type of scale allow the pickling acid to penetrate the scale layers and dissolve the inner layer causing the bulk of the scale to be removed in flakes After the iron oxides
