This report examines the influence of carbon content on the mechanical properties of steel. The study explores how varying carbon levels affect key characteristics such as tensile strength, ductility, hardness, weldability, and fracture toughness. The research investigates the classification of steel based on carbon content, differentiating between plain carbon, mild carbon, and high carbon steels, and analyzes how each type's properties are affected. The methodology includes a review of secondary sources, including books and journals, and discusses standard testing procedures like Brinell hardness and tensile testing using a UTM machine. The report highlights the inverse relationship between carbon content and steel toughness, as well as the impact on steel's ability to be hardened and welded. The findings emphasize the importance of understanding carbon content's role in optimizing steel's performance for various applications, balancing strength and ductility.
