DIN 2391 ST52 Cold Drawn Steel Pipe
DIN 2391 ST52 Cold Drawn Steel Pipe
DIN 2391 ST52 is a standard specification for seamless precision steel tubes. These tubes are primarily used in hydraulic and pneumatic power transmission applications. They have a high dimensional accuracy, and their surface finish is excellent. The ST52 designation stands for the material quality of the tubes, meaning that they have a minimum yield strength of 520 MPa.
