Cold Finishing and Cold Rolling

Cold finishing or cold rolling is an alloying process that mechanically deforms or works the metal at a temperature that is below the recrystallization point. Cold finishing or cold rolling processes squeeze the metal between two steel rolls. Drawing processes pull the metal from a die opening or gap. The elevated temperature allows a greater degree of deformation as well as annealing during the process. Cold finished or cold rolled products tend to have less scale on their surfaces than alloys produced by hot rolling.
