Therefore, cold rolled steel is identifiable by an oily and smooth surface. As the working takes place in temperatures below the rescrystallisation temperature, strain hardening occurs. The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel.

In case of carbon steels, cold rolling starts from hot-rolled and pickled coils, for thicknesses varying according to the type of steel, reducing its original thickness in percentages ranging from 30% for thick thicknesses and 90% for tinplate. This reduction can be obtained in cold rolling mills, which can be continuous, the so-called tandem (composed by up to 5 or 6 different stands), or ...

In cold rolling, the value is around 0.1; in warm working, a typical value is around 0.2; and in hot rolling, m is around 0.4. Hot rolling is often characterized by a condition called sticking, in which the hot work surface adheres to the rolls over the contact arc. This condition often occurs in the rolling of steels and high-temperature alloys. When sticking occurs, the coefficient of ...

Cold rolled steel is similar to hot rolled steel, but there are a few more steps involved in its manufacturing. It is rolled, pressed, stamped, and bent at room temperature, which maintains the strength and integrity of the steel. Next, the metal is processed further in cold reduction mills and allowed to cool after annealing and rolling. The finished product is shaped into flat sheets, coil ...
