DIN 2391 ST 30 Seamless Precision Steel Tubes are cold drawn seamless carbon steel tubes manufactured according to DIN 2391 standards for applications requiring high dimensional accuracy, excellent surface finish, and superior mechanical performance. These tubes are widely used in hydraulic systems, pneumatic cylinders, automotive components, engineering equipment, machine parts, and precision mechanical applications. The material offers excellent machinability, weldability, and pressure resistance while maintaining tight dimensional tolerances.

As a trusted DIN 2391 ST 30 seamless tube supplier, we provide precision-engineered tubes in various sizes, wall thicknesses, and lengths to meet the demanding requirements of global industries.

What are DIN 2391 ST 30 Seamless Precision Steel Tubes?

DIN 2391 ST 30 Seamless Precision Steel Tubes are high-quality cold finished seamless tubes manufactured under the DIN 2391 specification. The standard was developed to ensure precision tubing with strict dimensional tolerances and superior mechanical properties.

The tubes are produced through a cold drawing process that improves dimensional accuracy, surface finish, and mechanical strength compared to conventional hot-finished tubes. Because of these characteristics, DIN 2391 cold drawn precision tube products are extensively used in hydraulic cylinders, pneumatic systems, automotive engineering, and industrial machinery.

Industries prefer these tubes when accuracy, reliability, and consistent performance are critical to system operation.
