Pickling Time

The length of time a coil must be immersed in acid to descale the entire surface of the steel. It is dependent on: the acid type, concentration and temperature; the carbon or alloy content of the steel; the size of the rod or wire; and whether the coils are banded or unbanded. Times vary from 5 min or less for wire pickling after annealing, to 60 min or more for heavy alloy rod.
