Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing they recrystallize which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal like semi-finished casting products such as slabs blooms and billets.

Difference Between Hot and Cold Rolled Steel Metal

Difference Between Hot and Cold Rolled Steel Metal

Sep 11 2014 · Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.
