1, rigidity
Cold drawn flat steel has steel, flat steel steel steel is relatively soft,
2, smooth surface
Flat steel surface is smooth and clean, but cold drawn flat steel used in the advanced cold extrusion process to make the surface of cold-drawn steel products is smooth and bright, the degree of more than ordinary flat steel.
3, specification diversity
Cold drawn flat steel specifications, through the design of different shapes of molds, cold drawn different cross-section shapes, different specifications tolerance of cold drawn steel. Angle can be designed into a right angle or rounded. Flat steel products with special specifications, thickness in 8-50mm, width 150-625mm, length 5-15m, and product specifications gear spacing is dense.
4, saving material
Flat steel on the material savings than cold drawn flat steel. Cold drawn process is the raw material cold extrusion deformation to the required shape, specifications and tolerances, the loss of raw materials is very small, relative to the use of traditional lathe machining and cutting of materials consumed, cold drawn steel to save the material is very substantial, especially when the material dosage is large, the savings in material costs are more significant.
5, processing time and processing machinery savings
Cold drawn flat steel due to accurate precision, good surface condition, cold drawn steel products can be used directly, such as spraying, sanding, bending, drilling, but also according to the actual requirements of the fine pulling directly after the plating, eliminating the need for a lot of machining time and save the configuration of the cost of processing machinery.

When the temperature is lower than a specific temperature value, the material will be transformed into a brittle state, its impact absorption work decreased significantly, this phenomenon is called Cold brittle, so, the design also according to the working temperature of the component to select the appropriate cold brittle transition temperature of the material. Cold drawn seamless steel pipe deformation is too small, can not achieve the surface finish and dimensional accuracy requirements, cold drawn square steel can not reach the strength index of the component; deformation is too large, cold drawn flat steel plasticity, toughness reduction is too much, and, the grain is pulled too long and thin, the formation of a fiber organization, the metal will have a clear anisotropy. Cold-drawn seamless steel tube in the axial direction, parallel to the elongation direction of the grain, the strength of the elevated; cold-drawn flat steel radial direction, perpendicular to the elongation direction of the grain, the strength of the opposite reduction, and the maximum stress of the hydraulic cylinder exists in the radial direction of the seamless steel tube, so the deformation is too large for the full play of the cold-drawn tube is not conducive to the performance of the cold-drawn tube. In the process of low-stress brittle fracture that occurs in high-strength metal materials, the material organization is far from uniform and isotropic. There will be cracks in the organization, there will be inclusions, pores and other defects, these defects can be seen as microcracks in the material. In addition, brittle fracture is also related to the use of temperature of the component.
Difference between cold drawn flat steel and flat steel - """ Cold drawn flat steel: steel, surface flatness, flat steel: steel is relatively soft, flatness is not as good as cold drawn flat steel flat steel, refers to the width of 12-300mm, 4-60mm thick, the cross-section of the rectangular and slightly obtuse edge of the steel. Flat steel can be a finished steel, can also be used as billets for welded pipes and thin slabs for stacked rolled sheet. Main applications: flat steel as a finished material can be used for the production of hoop iron, tools and machinery parts, construction as a structural member of the frame, escalators ....
The difference between cold drawn flat steel and bright flat steel - "" The biggest difference is that the cold drawn flat steel is annealed and drawn with pickling; bright flat steel is produced by shot blasting process; but the shot blasting looks bright there is a print wound with the same cold drawn both can be produced depending on what you do with the product
