Aatir Steel, a top-notch manufacturer and supplier based in Cairo, Egypt, proudly presents its high-quality Carbon Steel EN-44 Bars, renowned for their remarkable strength, toughness, and durability. Crafted to meet international standards, these bars boast consistent dimensions, a smooth surface finish, and outstanding mechanical performance. Aatir Steel’s EN-44 Bars find their place in automotive, engineering, and industrial sectors where high stress, wear resistance, and reliability are crucial. With excellent machinability, hardenability, and fatigue resistance, these bars are perfect for precision engineering, forging, and heavy-duty mechanical applications, making them a go-to choice for industrial and structural projects throughout Egypt.
Carbon Steel EN-44 Bars mainly consist of iron, featuring a carbon content of 0.42–0.50%, manganese at 0.60–0.90%, chromium ranging from 0.70–1.00%, along with trace amounts of molybdenum, sulfur, and phosphorus. This blend results in impressive tensile strength, hardness, and toughness. Typically, the bars exhibit a tensile strength of 850–1050 MPa and a yield strength of 600–750 MPa, along with good elongation and impact resistance. Their high hardenability, wear resistance, and machinability make them ideal for heat treatment, forging, and precision machining, ensuring dependable long-term performance in demanding industrial settings.
