Carbon Steel DIN 2391-2 Pipes are high-precision steel tubes crafted to meet the German standard DIN 2391-2. They’re specifically designed for applications that demand exceptional dimensional accuracy, a smooth surface finish, and outstanding mechanical properties. These seamless, cold-drawn tubes find their place in hydraulic and pneumatic systems, mechanical engineering, automotive parts, and structural applications where strength, reliability, and precision are non-negotiable. Known for their uniform wall thickness, excellent roundness, and tight tolerances, DIN 2391-2 pipes are perfect for the rigorous demands of engineering and industrial settings.
Made from low carbon steels with carefully controlled levels of carbon, manganese, phosphorus, sulfur, and silicon, these pipes boast impressive tensile strength, good yield strength, and high toughness, all while allowing for precise cold drawing and machining. Mechanically, they excel in fatigue resistance, dimensional stability, and durability under internal pressure, dynamic loads, and mechanical stress. Their seamless design guarantees consistent performance and long-lasting reliability in hydraulic, pneumatic, and structural applications.
