Cold-formed steel (CFS) is the common term for steel products shaped by cold-working processes carried out near room temperature, such as rolling, pressing, stamping, bending, etc. Stock bars and sheets of cold-rolled steel (CRS) are commonly used in all areas of manufacturing. The terms are opposed to hot-formed steel and hot-rolled steel.
Cold Rolled steel has an improved surface finish and tighter tolerances compared to hot rolled steel. It is commonly used for parts requiring cold forming, such as crimping, swaging or bending. It can also be used for Shafts, machinery parts, bolts, pinions, gears, as well as in the creation of furniture, appliances and other consumer goods. ...
Cold rolled steel is stored and sold in coiled form after rolling. Steel comes in many grades, specifications, shapes, and finishes—the World Steel Association lists over 3,500 different grades of steel, each with unique properties. The various types mean that steel can by widely used in infrastructure, appliances, vehicles, wind turbines, and many more applications.
COLD-ROLLED STEEL. As you might suspect, the manufacturing process behind cold-rolled steel is a bit different. Despite the name, this process refers to steel that is pressed with the pressure of a roller at room temperature. Compared to hot-rolled steel, cold-rolled steel has a nearly 20% increase in strength through the use of strain hardening.
Tags Cold Rolling Mill, Hot Rolling Mill; The Differences Between Hot Rolling And Cold Rolling Presses. At American Steel, customers often ask us about the differences between hot rolled steel and cold rolled steel. Fundamentally, there are some differences between these two types of metal.
Hot Rolled Steel vs. Cold Rolled Steel. The difference between hot rolled and cold rolled steel is this recrystallization point. Cold rolling is done when the metal is able to form "new grains" as the old ones are deformed by rolling and bending the metal.

Jul 16, 2014· Cold rolled is the next step along the line of flat-rolled steel products. The process starts with hot rolled P&O. Hot rolled is processed to a final thickness that is heavier than most sheet products. A cold-reducing process is used, which results in a thinner thickness. The cold reduction starts with tension to the sheet.

Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.
