Hot rolling involves the production of sheet metal from billets by passing the steel through rollers while above its recrystallization temperature to desired physical dimensions. Multiple passes through the rollers may be necessary to produce the final dimensions. Hot rolled steel is relatively soft and ductile compared to cold rolled steel.
Electric Resistance Welded Tubing Industrial Tube and Cold rolled electric welded (CREW) tube is produced per ASTM A513 Type 2. CREW is produced from hot rolled strip steel that has been cold reduced. Due to the extra cold working at the steel mills, A513 Type 2 tubing will have tighter wall thickness tolerances, improved surface condition and a narrower range of mechanical properties than A513 Type 1.
Hot Rolled Steel is available in many shapes, grades and sizes. Choose from the selection below. Hot rolling involves the production of sheet metal from billets by passing the steel through rollers while above its recrystallization temperature to desired physical dimensions.

RollingHistoryHot and Cold RollingProcessesMillsDefectsIn metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling.
