DIN 2391 ST52 Seamless Precision Honed Tube

MULTISTEEL’s DIN 2391 St52 tubes have exceptional strength, durability, and precision. The name “DIN 2391” refers to the German industrial standard for precision seamless steel tubes, while “St52” is a specific grade of carbon steel known for its good tensile strength, durability, and excellent machinability.

With a carbon content of about 0.22%, ST 52 provides an optimal balance between strength and machinability. These tubes are produced through a seamless process, ensuring no welded seams, which enhances their structural integrity and reliability.

MULTISTEEL’s honed tubes are designed for hydraulic cylinders, offering smooth surfaces that ensure efficient piston movement. The honing process creates a polished inner surface, reducing friction, wear, and enhancing sealing efficiency under high pressure.

With a range of sizes and finishes, DIN 2391 St52 seamless precision tubes offer versatility for various industrial uses.

Applications of DIN 2391 ST52 Honed Hydraulic Cylinder Tube

• Hydraulic Cylinders: Commonly used in hydraulic systems where precise fluid control and smooth movement are critical, such as in construction, agricultural, and industrial equipment.

• Pneumatic Systems: Ideal for use in pneumatic cylinders and air compressors, where low friction and accurate dimensions are necessary.

• Automotive and Machinery: Used in the production of components that need to endure high pressure and require precise internal surfaces.

DIN 2391 ST52 tubes are manufactured using advanced techniques like scraping and rolling to improve their durability and performance. Scraping and rolling create a surface layer with residual compressive stress, effectively sealing minor cracks and enhancing corrosion resistance. This process delays the onset of fatigue cracks, significantly increasing the fatigue strength of the tubes.

The rolling process also forms a cold hardening layer on the inner surface, minimizing elastic and plastic deformation during contact. This improves wear resistance, reduces surface roughness, and enhances the matching properties of honed tubes for seamless integration into various hydraulic systems.
