What is the Difference Between Hot Rolled (HR) & Cold Rolled …
The main difference between hot and cold rolled steel is in how they are processed. Hot rolled steel is steel that has been rolled at high temperatures, while cold rolled steel is essentially hot rolled steel that is further processed in cold reduction materials. Here, the material is cooled followed by annealing and/or tempers rolling.

High Strength Cold Drawn Steel Bars
The first feature is size. Comparing to a hot rolled bar, which is formed (rolled) at high temperatures, a hot rolled bar will vary greatly in size, with a larger variance the bigger the diameter. Hot rolled bars will also have an oval or eggy-shape to it. Roundness on a cold finished bar will coincide with size, being half the size tolerance.
