Processing Technique

Cold drawing is a metalworking process that reduces the diameter of a tube while increasing its length at room temperature. This technique enhances dimensional accuracy and strengthens the material through strain hardening.

Following cold drawing, the tube undergoes honing, which uses scraping and rolling techniques to improve surface finish. This process introduces residual compressive stress, sealing small cracks and enhancing corrosion resistance.

Honed tube exhibits improved fatigue strength by delaying the growth of fatigue cracks. The combination of cold drawing and honing produces a durable, high-quality product ideal for demanding industrial applications.

Applications of ST52 Honed Tube

Hydraulic Cylinders: ST52 honed cylinder tubes are crucial components in hydraulic systems, providing a smooth inner surface that reduces friction and enhances efficiency.
Pneumatic Systems: ST52 honed tubes are used in pneumatic cylinders, ensuring reliable operation in air-powered machinery.
Automotive Industry: Commonly found in shock absorbers, steering systems, and other critical automotive components, they contribute to vehicle stability and performance.
