Specifically made for seamless precision steel tubes with specified inner and outer diameters, these pipes are manufactured in accordance with DIN 2391-2 specifications. Applications requiring high dimensional accuracy, like hydraulic systems, automotive parts, and instrumentation lines, frequently use DIN 2391-2 pipes. These pipes are available from Bulan in several grades, such as St 35, St 45, and St 52, which guarantee superior performance under mechanical stress and high pressure.
DIN 2391-2 Carbon Steel Steel grades such as St 35, St 45, and St 52 are used to make pipes. These grades contain small amounts of silicon, phosphorus, and sulphur, as well as carbon (≤0.22%) and manganese (up to 1.6%). Depending on the grade, these precision tubes have yield strengths between 235 and 355 MPa and tensile strengths between 340 and 630 MPa. They are well-known for their superior elongation (≥20%), tight dimensional tolerances, and excellent surface finish. They are also well-suited for high-performance and pressure systems due to their good cold formability and weldability.
