Carbon Steel DIN 2391-2 pipes are high-precision seamless pipes widely recognized for their superior dimensional accuracy, smooth internal surfaces, and excellent mechanical performance. These pipes are manufactured using cold-drawn or cold-rolled processes, making them ideal for applications requiring precision and reliability under high pressure. Industries such as automotive, hydraulics, machining, and engineering rely heavily on DIN 2391-2 pipes due to their consistency and durability. Their ability to withstand demanding operational conditions makes them a preferred choice for critical applications where strength, efficiency, and long service life are essential. These pipes adhere to strict German and international quality standards.
Carbon Steel DIN 2391-2 pipes typically contain 0.10–0.20% carbon for strength, along with manganese (0.30–0.70%) and silicon (up to 0.40%) to enhance hardness and structural integrity. Trace amounts of phosphorus and sulfur improve machinability. Mechanically, these pipes deliver high tensile strength ranging from 340 MPa to 520 MPa and yield strength between 235 MPa and 355 MPa. Their elongation rate (up to 25%) ensures good ductility, while the cold-drawn process provides superior surface finish, dimensional accuracy, pressure resistance, and fatigue strength.
