In automotive driving safety and power transmission, the steering system acts as the "control center," while the drive shaft tube serves as the "power bridge." Both place extremely stringent performance demands on the tubing materials. Seamless steel tubes, with their advantages of being weld-free, having a uniform structure, and stable mechanical properties, have become the ideal material choice for these two critical components. Changzhou Tenjan Steel Tube Co., Ltd., through its in-depth research and development of automotive-grade seamless steel tubes, provides the industry with high-quality products that precisely meet these demands.

I. Seamless Steel Tubes for Steering Systems: Precision and Fatigue Resistance are the Safety Baseline

The steering system must accurately transmit control commands; even the slightest deviation in the tube material can affect steering responsiveness and potentially lead to safety risks. Therefore, seamless steel tubes for steering systems must meet two core requirements: firstly, high precision, requiring inner and outer diameter tolerances to be controlled within extremely tight limits to ensure precise compatibility with steering components; secondly, strong fatigue resistance, necessitating excellent wear resistance and crack resistance to withstand the alternating stresses of frequent steering over the long term. Changzhou Tenjan Steel Tube utilizes precision cold drawing processes and quenching and tempering heat treatments to control the dimensional tolerances of its seamless steel tubes within ±0.05mm. Simultaneously, they enhance the material's yield strength and elongation, resulting in a fatigue life that is 20% higher than the industry average, making them perfectly suited for the steering system requirements of various vehicles, including passenger cars and commercial vehicles.

II. Seamless Steel Tubes for Drive Shaft Tubes: The Dual Test of Strength and Concentricity

The drive shaft tube is responsible for transmitting engine power to the wheels, enduring significant torque and vibration. The requirements for seamless steel tubes here focus on two points: firstly, high strength to resist the tensile and torsional stresses induced by torque, preventing deformation or fracture of the tube; secondly, high concentricity, as insufficient concentricity can easily cause vibration during high-speed rotation, affecting ride smoothness. To address the needs of drive shaft tubes, Tenjan Steel Tube selects high-strength alloy steel as the raw material and employs non-destructive testing technology to monitor the wall thickness uniformity and concentricity of the seamless tubes throughout the process. Additionally, each batch of products undergoes torque testing and vibration simulation tests to ensure the tubes can withstand long-term, high-load power transmission, meeting the requirements of drive shaft systems for vehicles with different engine displacements.

Whether meeting the precise control needs of steering systems or the power transmission demands of drive shaft tubes, high-quality seamless steel tubes are key to ensuring automotive performance. Focusing on "precisely matching the needs of the automotive industry," Changzhou Tenjan Steel Tube Co., Ltd. leverages refined processes and strict quality control to allow seamless steel tubes to fully realize their advantages in steering and drive shaft components. They have become a trusted partner for numerous automotive manufacturers and parts suppliers, strengthening the material foundation for automotive safety and power transmission.
