The cold drawn square bar is a kind of steel processed by cold drawing process, with high precision and good surface quality. In the production process, the hot rolled square bar is first pickled to remove the surface oxide, and then through multiple cold drawing or cold rolling, the steel is plastic deformed at room temperature, so as to achieve the purpose of improving the strength of the material and improving the dimensional accuracy. The cold drawing process can not only significantly improve the mechanical properties of the steel, but also greatly improve the surface finish. The following are the specific properties and characteristics of cold-drawn square bar:

1. High strength and high hardness?Due to the strong plastic deformation of the material during the cold drawing process, which leads to the internal grain refinement of the material and the increase in dislocation density, so that the cold-drawn square bar has higher strength and hardness than ordinary hot-rolled square bar. This characteristic makes cold-drawn square bar perform well when subjected to heavy or impact loads.

2. Good dimensional stability and accuracy?Cold drawing process can effectively control the dimensional accuracy of steel to ensure that the geometry of finished square bar is more regular and the dimensional deviation is smaller. This is especially important for mechanical parts that require a precise fit, which can reduce errors in the assembly process and improve the operating efficiency of the overall equipment.

3. Excellent surface quality? After cold drawing, the surface of the square bar is smooth and fine, no obvious scratches, cracks and other defects, reducing the need for subsequent processing processes and reducing production costs. At the same time, a good surface condition is also conducive to improving the appearance quality and corrosion resistance of the product.

4. Excellent machining performance? Cold-drawn square bar because of its high hardness and strength, in the machining process of cutting, drilling, tapping and other excellent performance, not easy to produce burrs, improve processing efficiency and product quality.

Application fields:

- Building structure: Cold-drawn square bar is widely used in high-rise buildings, Bridges, industrial plants and so on because of its good mechanical properties and dimensional stability. In these scenarios, cold-drawn square bar is often used as key components such as support structures and beam-column connectors to ensure the safety and stability of the building. Widely used in high-rise buildings, Bridges, industrial plants and so on.

- Machinery and equipment: used to manufacture heavy machinery, mining equipment, etc.

- Transportation: Structural parts for railway vehicles, ships and other means of transportation.
