Carbon Steel EN-24 Bars are alloy steels made from nickel, chromium, and molybdenum, typically containing 0.36–0.44% carbon, 1.3–1.8% nickel, 0.9–1.4% chromium, and 0.2–0.35% molybdenum, along with trace amounts of manganese and silicon. These bars are known for their outstanding tensile strength, toughness, and resistance to fatigue. Their mechanical properties include a tensile strength ranging from 850–1000 MPa, a yield strength of about 680 MPa, and impressive impact resistance, even in low temperatures. EN-24 can be heat-treated to achieve a perfect balance of hardness and ductility, making it ideal for challenging engineering applications.
