Known for its unwavering dedication to quality and precision, Yousef Steel delivers high-performance EN-24 bars that are perfect for demanding industrial applications. These bars stand out for their exceptional strength, toughness, and impressive fatigue resistance, making them a go-to choice for heavy-duty mechanical components. Catering to vital sectors like automotive, aerospace, power generation, and general engineering, Yousef Steel guarantees that all EN-24 bars are crafted to meet international standards, providing clients with durable and reliable solutions, along with timely delivery and outstanding customer support throughout the region.
Carbon Steel EN-24 Bars are crafted from a nickel-chromium-molybdenum alloy steel, featuring around 0.36–0.44% carbon, 1.3–1.7% nickel, 0.45–0.65% chromium, and 0.2–0.35% molybdenum. This unique blend results in remarkable strength, toughness, and wear resistance. Typically, EN-24 bars showcase a tensile strength ranging from 850 to 1000 MPa and a yield strength of about 680 MPa. The Brinell hardness falls between 248 and 302 HB. These bars are often supplied in hardened and tempered conditions, which boosts their mechanical properties for use in critical and high-stress industrial applications.

Carbon Steel EN-24 Bars find extensive use in scenarios that demand high tensile strength, shock resistance, and fatigue endurance. They are particularly well-suited for manufacturing automotive components like gears, shafts, crankshafts, axles, and drive shafts. In the aerospace and defense industries, they serve as structural components and high-load-bearing parts. EN-24 bars are also employed in heavy machinery, marine equipment, power generation turbines, and tooling systems. Their excellent machinability and ability to retain strength under dynamic loads make them ideal for components that face constant mechanical stress and challenging operating conditions.
