What is Cold-Rolled Steel? | Pacesetter
Cold-rolled steel is simply hot-rolled steel with additional processing to make it a smoother and more versatile material. Cold rolled steel is a versatile sheet metal product formed by passing a steel strip through a pair of rolls called "stands," which have been preheated to a specific temperature.
Hot Rolled vs. Cold Rolled Steel, What's all the Fuss About?
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. I buy hot rolled whenever I can for blacksmithing.

Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a yield strength of 365 MPa. The main advantages of cold working are: Accurate finished dimensions.
Cold Rolling - an overview | ScienceDirect Topics
Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the time of holding [35].
