Seamless precision steel tubes under the DIN 2391 standard are usually available in an outer diameter range of 16-325mm and a wall thickness range of 1-22mm. However, please note that the specific dimensions may vary depending on the application requirements.
DIN 2391 St45 carbon steel tube is a medium carbon steel material with tensile strength properties that are only moderate at best. The material can be treated through processes such as quenching and tempering.
DIN 2391 St45 seamless tube is widely used in hydraulic systems, such as manufacturing hydraulic cylinders and other key components in hydraulic systems. In addition, it is also suitable for other fields that require high precision and reliability, such as machinery manufacturing and automobile manufacturing.
