Cold Rolled Steel Sheet Metal Properties

Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature.

Cold rolled steel sheet metal properties.

When steel is formed by press braking or cold rolled forming there is a change in the mechanical properties of the material by virtue of the cold working of the metal. Hillman 8 in x 24 in cold rolled steel solid sheet metal. For end users cold rolling deteriorates the stamping performance and the product is suitable for simple deformed parts. Cold rolled has sharper corners and more precise dimensions than hot rolled.

The change of cold rolled steel shape is a continuous cold deformation and the cold hardening of this process causes the strength hardness and toughness of hard rolled coil to decrease. That s because cold rolling is a technique for forming the steel whereas hdg is a technique for treating it to protect it from corrosion. Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio. To meet the various end use requirements cold rolled sheet products are metallurgically designed to provide specific attributes such as high formability deep drawability high strength high dent resistance good magnetic properties enamelability and paintability.

As an example a hot rolled steel product may have a yield strength of 235 mpa. Cs type b. Cold rolling and galvanization are not mutually exclusive and in fact cold rolled steel can be galvanized. When a steel section is cold formed from flat sheet or strip the yield strength and to a lesser extent the ultimate strength are increased as a result of this cold working particularly in the bends of the section.

In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. Ds type b. As a registered iso 9001 2015 company rolled steel products state of the art equipment meets virtually any requirement in panel flat quality leveling precision slitting close tolerance sheet blanking strip quality edge conditioning precision shearing and complete cold reducing capabilities. Cold rolled 1008 1010 steel physical properties.

The rolls induce plastic deformation. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. For pricing and availability.
