Carbon Steel DIN 17121 Pipes are manufactured through carbon steel of high quality having compositions generally ranging from 0.17–0.23% Carbon, 0.30–0.60% Manganese, and traces of Sulphur and Phosphorus. DIN 17121 carbon steel pipes possess superior mechanical properties like low yield strength of 235–355 MPa and tensile strength of 340–650 MPa, based on the grade. They are good for formability, weldability, and toughness. These make the DIN 17121 carbon steel pipes very ideal to use in structural applications where strength and durability are of essence.
