Hot Rolled Steel vs. Cold Rolled Steel (Ultimate Difference

Hot rolled and cold rolled are the process of steel plate or profile forming. They have a great influence on the structure and performance of steel.. The rolling of steel is mainly hot rolling, and cold rolling is usually used only for the production of steel with precise sizes such as small-sized section steel and thin plates.

Cold Rolling - process overview - EngineeringClicks

Rolling is an important function of the steel industry. It’s a steel fabrication process involving passing the metal through a pair of rollers. There are two main types of rolling process: Flat rolling – the finished product is a sheet Profile rolling – the finished product is a bar or rod. The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a temperature typically above 900° C, greater than its recrystallisation temperature. This allows steel sheets
