What is the Difference Between Hot Rolled (HR) & Cold Rolled (CR) Steel?

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. Steels of different grades and specifications can be either hot or cold rolled. Understanding the differences between hot and cold rolled steel can help you determine the best type for your needs.
