How hot-rolled sheets are made

Sheet metal is produced by rolling. It involves forcing a heated billet of metal through a series of shafts that give it the desired shape and thickness. In the case of hot-rolled sheets, this takes place at a temperature higher than the recrystallization temperature of steel, i.e. approx. 600 degrees C. This allows the use of less force and easier shaping during processing, and prevents damage to the processed material. On the other hand, the destruction and re-formation of the crystalline structure of steel means that the sheet does not retain its pre-processing properties and becomes less elastic.
