Hot rolled sheet

Listing ID #4876699

Hot Rolled (HR) Steel Sheets are made using the hot rolling process, in which the semi-finished products, such as steel slabs or billets, are first made into thin sheets by rolling them between rollers. During the process, special care is needed to ensure the temperature of the furnace does not drop below the steel’s recrystallization temperature. If in any circumstances, the temperature drops below the recrystallization temperature, the material has to be reheated all over again.

After rolling, the resultant product is annealed and converted into various forms by cutting them mechanically or by burning.

Hot rolled steel often consists of oxide layers which are treated by the pickling process. In this treatment, an acid-based pickling solution is used to remove surface scales and impurities from the metal to give a bright surface finish to the steel sheet.
