Pickled Steel sheet

The surface of Hot-Rolled products is oxidized due to the High rolling temperature, therefore, there is some inhomogeneity in its Properties such as thickness, color and … . In Seven Diamonds Industries Company, these products are descaled by hydrochloric acid in pickling process to achieve the quality for subsequent uses.
