The Alloy Steel AISI 4140 bars and rods are produced using cutting-edge metallurgical techniques, guaranteeing consistent performance, strength, and reliability. Tariku Metals is proud to set the bar high in the industry, both in Ethiopia and beyond.
The Alloy Steel AISI 4140 bars and rods are primarily made of iron, featuring a composition of 0.38–0.43% carbon, 0.8–1.1% chromium, 0.15–0.25% molybdenum, 0.75–1.0% manganese, and 0.2–0.35% silicon. This meticulously balanced mix results in outstanding hardness, tensile strength, and toughness. The steel typically boasts a tensile strength of 95,000–100,000 psi, a yield strength of 60,000 psi, and an elongation of 20%, making it highly resistant to wear and fatigue. Heat treatment further boosts its mechanical properties, enabling it to perform reliably under high-stress conditions in demanding industrial settings.
