Carbon Steel EN-9 is a medium carbon steel that contains about 0.50–0.60% carbon, along with a small percentage of manganese (0.70–1.00%). It boasts high tensile strength ranging from 550–700 MPa and good wear resistance, particularly when hardened and tempered. While it may not be as easy to weld as low-carbon steels, EN-9 machines well and responds effectively to heat treatment, enhancing its strength and toughness. It maintains dimensional stability during machining and strikes a good balance between hardness and machinability, making it suitable for medium-duty mechanical parts and components that require moderate toughness.
