The mechanical properties of the steel.

Cold rolled sheet steel properties.

Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. In general cold rolled has better mechanical properties than hot rolled. 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. Cold rolled steel is essentially hot rolled steel that has had further processing.

Alliance steel offers a variety of cold rolled steel sheet and coil products and value added services to meet customer needs. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. The rolls induce plastic deformation. 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.

Some of the main properties of cold formed steel are as follows. As the working takes place in temperatures below the rescrystallisation temperature strain hardening occurs. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. Chemically it is very similar to a36 hot rolled steel but the cold rolling process creates a better surface finish and better properties.

Therefore cold rolled steel is identifiable by an oily and smooth surface. Cold rolled is more expensive than hot rolled. 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. Cold rolled steel is rolled at room temperature below its recrystallization temperature which enables better control over finished product shape thickness dimensions and surface finish.

Cold rolled commercial quality sheet or coil steel supplied for either exposed or unexposed applications where bending welding forming or moderate drawing is involved. 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. Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio. The most commonly available of the cold rolled steels it has a good combination of all of the typical traits of steel strength some ductility and comparative ease of welding and machining.

This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. Crcq is available in coil sheet or strip formed with various gauge ranges widths and hardness. Tight control over chemical composition hot rolling parameters amount of cold reduction annealing time and temperature and the amount of temper rolling allow the production of high quality cold rolled steel products to meet customer requirements.
