Surface finish: HR sheets have a rough, scaly, bluish-grey finish due to the high-temperature rolling and subsequent cooling. Dimensional accuracy: They have less precise dimensional tolerances and slightly rounded edges compared to cold-rolled steel, as the steel can shrink non-uniformly as it cools. Mechanical properties: Hot rolling increases the ductility and toughness of the steel. Internal stresses: The process of cooling at room temperature normalizes the steel, making it free from the internal stresses caused by work-hardening. Versatility: HR sheets are a major raw material source in manufacturing and infrastructure due to their robust mechanical properties and affordability.
