Cold Drawn EN10305-4 E235 Hydraulic Carbon Steel Pipe uses E235 grade mild steel as the main material. E235 steel is known for its good weldability, formability, and mechanical properties, making it particularly suitable for applications that require high precision and good toughness. The low carbon content makes it easy to control deformation during processing, while ensuring the stability and reliability of the final product.
Manufacturing process:
The production of this tube is made using the cold drawing process, which is a processing method in which hot-rolled or cast raw materials are drawn several times through a die to reduce their cross-sectional area and increase their length. During the cold drawing process, the steel pipe not only undergoes a change in physical dimensions, but also eliminates the internal stress through intermediate annealing treatment, which improves the microstructure compactness and mechanical properties of the material. Compared to hot or cold rolling, the cold drawing process can significantly improve the accuracy and surface quality of the tube, making it more suitable for hydraulic systems with high requirements for dimensional accuracy and surface finish.
Key features:
High precision: The cold drawing process ensures high dimensional accuracy and straightness of the tubes, reducing errors and leakage risks during installation.
Good mechanical properties: E235 steel has good strength and toughness, and is able to withstand high pressure and frequent stress changes in hydraulic systems.
Excellent corrosion and abrasion resistance: After proper surface treatment (e.g. black phosphating), a protective film is formed on the surface of the pipe, which effectively resists the invasion of corrosive media and abrasion.
Long life: The combination of high-quality materials and exquisite workmanship makes this tube have a long service life and reduce maintenance costs.
Application:
Cold Drawn EN10305-4 E235 Hydraulic Carbon Steel Pipe is widely used in hydraulic systems in the automotive industry, including but not limited to the following:
Brake system: As the main material of the brake oil pipe, it ensures the fast response and stable performance of the brake system.
Steering: In hydraulic power steering, this tubing transmits power and helps the driver easily control the direction of the vehicle.
Suspension: Some high-end models use hydraulic suspension, and this tube plays a key role in this.
Cooling system: Some automotive cooling systems are hydraulically driven, and this type of pipe is also suitable.
Conclusion:
Cold Drawn EN10305-4 E235 Hydraulic Carbon Steel Pipe occupies a pivotal position in the automotive industry due to its excellent performance and wide range of applications. Its high precision, good mechanical properties, excellent corrosion and wear resistance, and long life make it an indispensable part of the hydraulic system. With the continuous development of the automotive industry, the requirements for hydraulic pipes will also increase, and this pipe will continue to play an important role in the future due to its excellent properties.
