What is cold rolled steel?


Cold rolled steel is a mill product produced from a hot-rolled pickled coil that has experienced substantial cold reduction at room temperature. The usual end product is characterized by improved surface, greater uniformity in thickness, and improved mechanical properties as compared with hot-rolled sheet. This occurs when the metal below its re-crystallization temperature, which increases the strength via strain hardening up to 20%.
Q&A Related to "What is cold rolled steel?"
Cold rolled steel is made by passing the steel through a number of rollers after the metal has cooled from initial production. The steel is reduced in thickness incrementally as it
