This means clients get top-notch materials that can handle tough environments, ultimately boosting the efficiency and lifespan of their projects.
Alloy Steel 4140 Coil is primarily made of iron, featuring 0.38–0.43% carbon, 0.8–1.1% chromium, 0.15–0.25% molybdenum, and 0.75–1.0% manganese. This combination provides a great balance of strength and toughness. It showcases impressive mechanical properties, including high tensile strength, yield strength, and fatigue resistance, along with good hardness and wear resistance after heat treatment. The steel also maintains excellent hardenability and can be tempered to find the perfect balance between toughness and hardness, making it a reliable choice for applications that need both durability and structural integrity under heavy loads or high-stress situations.
