Tariku Metals, located in Addis Ababa, Ethiopia, stands out as a top manufacturer and supplier of high-quality steel products. One of their flagship offerings is the Alloy Steel AISI 4340 Bars and Rods, which are celebrated for their remarkable strength, toughness, and reliability. These products are meticulously designed to meet industrial and engineering standards, making them perfect for a variety of applications in challenging environments. By blending advanced manufacturing techniques with rigorous quality control, Tariku Metals ensures that their products deliver consistent performance. The company has built a solid reputation as a trusted partner in sectors like automotive, aerospace, and heavy machinery, providing durable and high-performance alloy steel solutions.
The Alloy Steel AISI 4340 Bars and Rods are primarily made of iron, featuring about 0.38–0.43% carbon, 0.60–0.80% manganese, 0.70% chromium, 1.65% nickel, and 0.20–0.30% molybdenum. This careful alloying process gives the material exceptional mechanical properties, such as high tensile strength (up to 1080 MPa), excellent yield strength, and outstanding toughness. It also shows good fatigue resistance, wear resistance, and hardenability, making it ideal for heat treatment processes. The balanced mix of strength and ductility ensures reliable performance even under dynamic and high-stress conditions, making it a go-to choice for critical structural and mechanical applications.
