Cold drawn hexagonal steel refers to a product that improves the surface quality and mechanical properties of hot-rolled hexagonal steel materials by drawing and deforming them through cold processing. The production process and characteristics of cold drawn hexagonal steel will be introduced below.

The production process of cold drawn hexagonal steel mainly includes the following steps:

Raw material selection: The manufacturing of cold drawn hexagonal steel usually uses high-quality hot-rolled hexagonal steel as the raw material. The quality of raw materials is crucial to the performance of the final product.

Acid pickling and rust removal: Firstly, the hot-rolled hexagonal steel is subjected to acid pickling and rust removal treatment to remove surface oxide skin and impurities, preparing for subsequent cold processing.

Cold drawing: Send the pickled hexagonal steel material into a drawing machine for cold drawing process, and draw it into the specified size of hexagonal steel as needed. During the cold drawing process, the hexagonal steel material undergoes deformation such as tension and compression, resulting in refined grains, uniform internal structure, and improved mechanical properties of the material.

Straightening and cutting: The cold drawn hexagonal steel needs to be straightened to remove potential internal stress and maintain straightness. Then, according to the requirements, cut the cold drawn hexagonal steel to obtain the required length of the product.

Cold drawn hexagonal steel has the following characteristics:

Excellent surface quality: The surface of cold drawn hexagonal steel is flat and smooth, without obvious defects such as oxide skin, scratches, and dents. Compared with hot-rolled hexagonal steel, it has better surface quality and is suitable for fields that require high surface quality, such as mechanical processing, decorative materials, etc.

High mechanical properties: Cold drawn hexagonal steel, after cold processing, has refined grains and enhanced mechanical properties such as tensile strength, yield strength, and hardness due to deformation. Therefore, cold drawn hexagonal steel has better strength and durability under load.

Accurate Size: The size control of cold drawn hexagonal steel is relatively precise, with good dimensional stability. It can produce products of different specifications and lengths according to customer needs, providing better dimensional consistency and reliability.

The widespread application of cold drawn hexagonal steel:

Mechanical processing: Cold drawn hexagonal steel is widely used in the field of mechanical manufacturing. Due to its excellent surface quality and high mechanical properties, it can be used to manufacture various mechanical components, such as bolts, nuts, bearing seats, etc.

Architectural decoration: Cold drawn hexagonal steel is also used in building decoration materials. Its excellent surface quality and regular hexagonal shape make it commonly used in the production of decorative components such as railings, guardrails, and stair handrails.

Energy industry: Cold drawn hexagonal steel is widely used in the energy industry. For example, in the manufacturing of solar brackets, cold drawn hexagonal steel can provide a high-strength and precisely sized support structure.

Automotive industry: Cold drawn hexagonal steel is also used in the field of automotive manufacturing. It can be used to manufacture automotive components, such as engine parts, transmission system parts, etc. Its high strength and durability can improve the safety and reliability of automobiles.

In summary, cold drawn hexagonal steel has excellent surface quality, high mechanical properties, and dimensional accuracy through cold processing. It is widely used in fields such as mechanical manufacturing, building decoration, energy industry, and automotive industry. With the development of related industries and the increase in demand, the market prospects for cold drawn hexagonal steel are broad.
