Maduka Metals is a leading manufacturer and supplier of high-quality steel products based in Abuja, Nigeria. With a strong commitment to precision engineering and customer satisfaction, the company specializes in the production and distribution of 1141 Cold Drawn Bar and Rod. Renowned for their superior strength, machinability, and surface finish, these bars and rods meet international standards for industrial and engineering applications. Maduka Metals leverages advanced manufacturing processes and strict quality control measures to ensure consistent product performance, serving diverse sectors including automotive, construction, and machinery across Nigeria and beyond.
The 1141 Cold Drawn Bar and Rod is a medium-carbon, manganese steel that contains about 0.37–0.45% carbon, 1.35–1.65% manganese, 0.04–0.09% phosphorus, and trace amounts of sulfur to boost machinability. This grade is celebrated for its outstanding strength, hardness, and wear resistance after heat treatment. Typical mechanical properties include a tensile strength ranging from 620 to 750 MPa, a yield strength of around 415 MPa, and good ductility with an elongation of 15–20%. Its cold-drawn finish enhances dimensional accuracy, surface quality, and mechanical properties compared to hot-rolled options.
