Comparative Studies of Locally Produced and Imported Low-Carbon Steels on the Ghanaian Market

Journal of Natural Sciences, 1(1), pp. 15-22.

A comparative research on the mechanical properties and microstructural studies of locally produced and imported low-carbonsteels have been conducted. These low-carbon steels have played major roles in the building and fabrication industries in Ghana.Twodifferentbatches of samples (rebars) from local and foreign producers were used. The rods were obtained from the dealers on the open market. The chemical analyses werecarried out at Tema Steel Works Company Ltd.The tensile tests, hardness measurements and microstructural studies were carried on both the local and the imported steels. The results showed that, the imported rods were more ductile, with higher toughness values and percentage elongation than the locally produced samples. The locally produced rods, however, had higher ultimate tensile strength, higher hardness and were more brittle than the imported samples. The differences in the mechanical properties of the samples were attributed to the different elemental compositions and the production methods used.
