Samuel Steels, located in Abuja, Nigeria, has built a solid reputation as a manufacturer and supplier of top-notch Carbon Steel DIN 17173 Pipes, designed for durability, performance, and precision. These pipes are crafted in line with the German Standard DIN 17173, making them perfect for high-temperature and pressure applications. Samuel Steels takes quality control seriously, employing advanced production techniques to ensure their products meet international standards. The Carbon Steel DIN 17173 Pipes find extensive use in industries like oil and gas, chemical processing, and power generation, thanks to their remarkable resistance to stress, corrosion, and thermal expansion in tough environments.
These pipes are primarily made of iron and carbon, with carefully controlled amounts of manganese, silicon, phosphorus, and sulfur to boost their mechanical strength and machinability. They showcase impressive tensile strength ranging from 410 to 560 MPa and yield strength between 240 and 350 MPa. With excellent toughness, ductility, and weldability, they maintain stability even under high temperatures and pressures. Their well-balanced composition ensures outstanding formability and resistance to wear, oxidation, and corrosion, making them ideal for critical industrial applications.
