Cold Rolled Steel Sheet Metal Properties

Cs type b.

Cold rolled steel sheet metal properties.

As an example a hot rolled steel product may have a yield strength of 235 mpa. Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. For pricing and availability. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish.

Cold rolled has sharper corners and more precise dimensions than hot rolled. Cold rolling and galvanization are not mutually exclusive and in fact cold rolled steel can be galvanized. Hillman 8 in x 24 in cold rolled steel solid sheet metal. Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio.

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. In general cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated and provides a better overall surface finish. Hillman 8 in x 24 in cold rolled steel solid sheet metal. 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.

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. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. Cold rolled 1008 1010 steel physical properties. 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.

Ds type b. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. For end users cold rolling deteriorates the stamping performance and the product is suitable for simple deformed parts.
