Medium carbon steel is a type of steel that contains approximately 0.3% to 0.6% carbon by weight. This composition gives it a balance of strength and ductility, making it suitable for various applications, including automotive parts and machinery components. It is often used in situations where a combination of toughness and wear resistance is required. The heat treatment process can enhance the properties of medium carbon steel, allowing it to achieve higher hardness levels. Commonly used in the manufacturing of gears, shafts, and axles, this steel type is valued for its ability to withstand stress while maintaining form and function.
