In this case, the hot rolled steel is pickled in acid to remove the mill scale and then oiled to keep it from rusting. The cost is somewhere in between that of regular hot rolled and cold rolled. Finally, in my experience, the more popular (to the steel yard) sizes of mild steel usually come in both cold and hot rolled.

COLD-ROLLED STEEL. As you might suspect, the manufacturing process behind cold-rolled steel is a bit different. Despite the name, this process refers to steel that is pressed with the pressure of a roller at room temperature. Compared to hot-rolled steel, cold-rolled steel has a nearly 20% increase in strength through the use of strain hardening.
