Stainless Steel Cold Rolled Sheet: Which Is Suitable For You?

In the production of steelproducts, steel is molded and reshaped with different machinery at differenttemperatures. Rolling produces flat steel sheets of a specific thickness andthe process is steel rolling involves metal stock passing through a pair ofrolls.

The classifications of Stainless Steel Cold Rolled Sheet are important and people need to understand thedifference. If the temperature of the metal is below its recrystallizationtemperature, the process is termed as cold rolling. The process is classifiedaccording to the temperature at which the metal is rolled. If the temperatureof the metal is above its recrystallization temperature, then the process istermed as hot rolling.

Hot Rolled Steel: This process removes any induced stresses andgrain deformation due to the elevated working temperature.  Hot rolling is used mainly to produceproducts like sheet metal or simple cross sections, such as rail tracks and I-beams.

Cold Rolled Steel: Cold rolling helps in hardening andstrengthening the material thus improving the material¡¯s mechanicalproperties.  It also improves the surfacefinish and holds tighter tolerances.  Cold-rolledproducts often include similar hot rolled products like sheets and bars, butare usually smaller.

During the cooling process,non-uniformed cooling may occur, which results in residual stress of theproduct.  However, room temperature StainlessSteel Cold Rolled Sheet is less malleable than hot steel, so cold rollingcannot reduce the thickness of a work piece as much as hot rolling in a singlepass.  

Cold Drawn Steel: Cold drawing steel is similar to cold rollingbut instead of producing a flat object it produces steel like a coke can. Itmakes steel into the form of a wire like the spokes of a wheel or a paper clip.The room temperature steel is pulled through the die which reshapes it into athinner shape while maintaining the same volume.
