Typically, EN-9 bars are crafted from medium carbon steel, featuring a carbon content of around 0.50% and manganese levels up to 0.80%. This specific composition results in a tensile strength ranging from 550 to 700 MPa and a yield strength of about 300 to 400 MPa, depending on the heat treatment applied. EN-9 steel is known for its good wear resistance and can be hardened using heat treatment techniques like quenching and tempering. It also maintains decent machinability and can be welded effectively with the right preheating and post-weld treatment. EN-9 is usually available in black or bright bar finishes, offered in normalized, annealed, or hardened and tempered states.
