Why do we use 15-18% HCl for pickling

My pickling line will soon enter into its production phase.18% HCl will be used for pickling steel strips.I am keen to know what are the factors that effect the pickling time? I.e.,the optimum time for which a unit area of the strip should be in contact with acid bath to achieve pickling.
