Cold drawn hexagonal steel and its applications
2024-06-07 16:321、 Definition of cold drawn hexagonal steel
Cold drawn hexagonal steel refers to hexagonal steel made by cold drawing process. Cold drawing process is a processing method of drawing steel at room temperature, which can deform it and obtain the desired shape and size. Compared to hot rolling process, cold drawing process can produce more precise dimensions and more complex shapes.
2、 Characteristics of Cold Drawn Hexagonal Steel
1. High strength: Cold drawn hexagonal steel has high tensile strength and yield strength after cold drawing processing, and can withstand large pressure and bending stress.
2. Good plasticity and toughness: Cold drawn hexagonal steel undergoes plastic deformation during processing, which gives it good plasticity and toughness, and is not easy to brittle fracture.
3. High precision: Due to the ability of cold drawing technology to obtain very precise dimensions and shapes, the precision of cold drawn hexagonal steel is relatively high.
4. Smooth surface: After cold drawing processing, the surface of the steel is very smooth and not easy to rust.
3、 Production process of cold drawn hexagonal steel
The production process of cold drawn hexagonal steel mainly includes the following steps:
1. Preparation of billets: Select suitable billets and perform cleaning and pre-treatment.
2. Heating: Heat the billet to a certain temperature to soften it and make it easy to deform.
3. Perforation: Perforate the heated billet to form hexagonal holes.
4. Drawing: The perforated billet is pulled multiple times to gradually deform into a hexagonal shape.
5. Cooling: Cool the drawn steel to restore it to room temperature.
6. Straightening: Straighten the cooled steel to improve its flatness.
7. Quality inspection: Conduct quality inspection on the finished products, and once they pass the inspection, they can be stored in the warehouse.
4、 Classification of Cold Drawn Hexagonal Steel
According to different classification standards, cold drawn hexagonal steel can be divided into the following types:
1. According to specifications: According to the specifications and dimensions of the steel, it can be divided into different specifications of cold drawn hexagonal steel.
2. According to accuracy: According to the accuracy level of steel, it can be divided into two types: ordinary accuracy and higher accuracy.
3. According to the surface treatment method: According to the surface treatment method of steel, it can be divided into different types such as galvanizing, spraying, painting, etc.
4. According to material: According to the different materials of steel, it can be divided into different types such as carbon steel, alloy steel, stainless steel, etc.
5、 The use of cold drawn hexagonal steel
Due to its excellent mechanical properties, high precision, and smooth surface, cold drawn hexagonal steel is widely used in the following fields:
1. In the field of construction: Cold drawn hexagonal steel can be used to manufacture supports, connectors, etc. for building structures, such as bridges, high-rise buildings, etc.
2. Mechanical manufacturing field: Cold drawn hexagonal steel can be used to manufacture various mechanical parts, such as bolts, nuts, shaft sleeves, etc.
3. Automotive manufacturing field: Cold drawn hexagonal steel can be used to manufacture automotive parts, such as transmission shafts, suspension arms, etc.
4. Hardware products field: Cold drawn hexagonal steel can be used to manufacture various hardware products, such as doors and windows, furniture, etc.
