Cold Rolled Steel | AK SteelAK Steel can directly affect the mechanical properties of the steel. 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 highquality Cold Rolled Steel products to meet customer requirements.
Cold rolled steel is produced by further processing hot rolled steel through cold reduction mills (at room temperature) followed by annealing and/or temper rolling to produce steel with closer dimensional tolerances and a wider range of surface finishes.
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. For end users, cold rolling deteriorates the stamping performance, and
Cold rolling is the process whereby steel is treated below its recrystallization temperature which is versus to hot rolled steel to produce uniform, flat steel coils. Not only does this compress the thickness of the material, but it also boosts tolerance, improves tensile strength, and smooths surface finishing by hardening the inner strains of the metal.
Cold Rolled Steel Sheet & Coil. Alliance Steel offers a variety of cold rolled steel products and value added services to meet customer needs. Alliance Steel’s cold rolled steel service capabilities include slitting, shearing, blanking, leveling, degreasing and brushing and metallurgical support.
Sep 11, 2014 · Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.
CR sheets or cold rolled sheets are hot rolled products which provides a superior surface finish, with improved physical properties of the steel, such as high formability, high strength, excellent dent resistance, good magnetic properties, tensile strength, and workability and welding properties.
Cold rolled steel coil is a type of steel coil product developed from hot rolled steel coil and sheet, surface quality and dimension precision are quite low after hot rolling process, it can’t be used where surface quality and dimensions are required.
Therefore, cold rolled steel is identifiable by an oily and smooth surface. As the working takes place in temperatures below the rescrystallisation temperature, strain hardening occurs. The rolls induce plastic deformation. Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa.
In the process of cold rolling, the steel is annealed, during which coils heat the steel to its melting point. The steel is then allowed to cool slowly to room temperature in still air. This annealing process recrystallizes the steel for greater ductility, but because the steel is worked at room temperature, it maintains its strength.

Cold Rolled Steel Coil Supplier Cold rolled steel is low carbon hot rolled steel that has been cleaned of oxide scale and then finished in a specific series of rolling to just over the desired thickness, heating to controlled temperatures, and final rolling to the desired thickness.
CR COILS and Sheets. C. R. Sheets/ Coils. CR sheets or cold rolled sheets are hot rolled products which provides a superior surface finish, with improved physical properties of the steel, such as high formability, high strength, excellent dent resistance, good magnetic properties, tensile strength, and workability and welding properties.
3 Cost of Hot Rolled Steel vs. Cold Rolled Steel. Generally, the cost of cold rolled steel could be twice as much as the cost of hot rolled steel, as cold rolling is a More complex metal working process than hot rolling. There is also another finishing between hot rolling process and cold
Jul 16, 2014 · The material then undergoes temper rolling. The process of temper rolling consists of cold rolling the material with a very low reduction. This finishing process helps with surface finish and flatness of the final cold rolled product. The finished cold rolled coil is
Cold Rolled Steel. Cold rolled steels provide excellent thickness and flatness tolerances, surface finish, and press formability. We manufacture low and ultra low carbon grades to meet a variety of customer formability requirements, specified strength levels, and dent resistance requirements.
Cold rolled coil, strip and sheet. A wide selection for a variety of use; our cold rolled coil, strip and sheet products are available in both heat and corrosion resistant forms. In addition, their standard and special surface finishes provide a unique level of customization.
The cold rolled process creates a finished product that is more precise dimensionally than a hot rolled product. This is because it is already closer to the finished dimension since it has already gone through the cooling process. Unfortunately, because of these properties, cold rolled steel is limited to just a few shapes, such as round, square, flat and variations of those types of shapes. Other shapes can be cold
