Carbon Steel DIN 17121 pipes are top-notch seamless and welded structural steel pipes crafted in line with the German standard DIN 17121. These pipes are built for structural applications where strength, durability, and resistance to mechanical stress are key. You’ll find them widely used in construction, mechanical engineering, and various structural purposes. Irfan Pipes and Tubes, based in Istanbul, Turkey, supplies pipes that meet DIN 17121 standards, ensuring precision manufacturing and adherence to international quality benchmarks. With their reliable performance and outstanding mechanical properties, these pipes are trusted across industries for demanding structural and load-bearing tasks.
Typically, DIN 17121 Carbon Steel Pipes are made from grades like St37-2, St52-3, and RSt37-2. Their chemical makeup includes carbon (up to 0.22%), manganese (up to 1.60%), phosphorus (≤0.045%), and sulfur (≤0.045%). These grades are known for their excellent weldability and forming capabilities. Mechanically, the pipes boast tensile strengths ranging from 340 to 630 MPa and yield strengths between 235 and 355 MPa, depending on the grade. Elongation falls between 21% and 26%, showcasing good ductility. These characteristics make DIN 17121 pipes perfect for high-load applications where stability, strength, and resilience are essential.
