Aatir Steel stands out as a top manufacturer and supplier of Alloy Steel 4140 Coils right in Cairo, Egypt. We take pride in offering high-quality alloy steel products that are built for exceptional strength, toughness, and reliability. Our Alloy Steel 4140 Coils are specifically designed to thrive in tough industrial environments, providing outstanding wear resistance, fatigue strength, and dimensional stability. With cutting-edge technology and rigorous quality control in our manufacturing process, Aatir Steel guarantees consistent mechanical performance and precision. These coils find their place in various sectors, including automotive, engineering, and construction, delivering robust and dependable solutions for components that demand high strength, toughness, and long-lasting operational efficiency.
The composition of Alloy Steel 4140 Coils includes carbon (0.38–0.43%), chromium (0.80–1.10%), molybdenum (0.15–0.25%), manganese (0.75–1.00%), along with small amounts of silicon and sulfur. This blend strikes the perfect balance between hardness, strength, and toughness. The mechanical properties showcase a tensile strength ranging from 655–950 MPa, a yield strength of about 415 MPa, and an elongation of 20%. These coils are heat-treatable, which enhances their hardness and mechanical performance, making them ideal for high-stress, wear-intensive, and fatigue-sensitive industrial applications.
