Hot-Rolled Pickled and Oiled

Steel pickling and oiling is a type of metal surface treatment finish to remove surface impurities like rust and carbon scale from a hot-rolled steel product. The steel is dipped into a bath of pickle liquor which consists of hydrogen chloride acid solution. The oiling process is similar but the solution the material is dipped into consists of a water-soluble or a mineral-based oil to help prevent flash rust while the material waits for further fabrication.
