Medium-Carbon Steel:
With carbon content usually between 0.30% and 0.60%, medium-carbon steel exhibits higher hardness and strength, making it suitable for applications requiring significant loads and pressures. It is often used for the gears and shafts of gearbox mainshafts, ensuring durability and long life. Different medium-carbon steel materials possess varying characteristics and applicability, so choosing the right medium-carbon steel depends on specific application needs. Materials like 1045 steel, with a carbon content of around 0.45%, offer excellent forgeability and weldability and are commonly used in the manufacture of mechanical parts such as bolts, bearings, and shafts. These materials strike a balance between hardness and strength while maintaining a certain degree of forgeability and weldability, making them highly practical for producing various engineering components and parts.
Low-Carbon Steel:
With carbon content typically ranging from 0.05% to 0.30%, low-carbon steel offers lower hardness and is easier to machine and shape. It is commonly used for other components of the mainshaft, such as housings and support structures. A material like 1018 steel, with a carbon content of approximately 0.18%, boasts excellent machinability and forgeability and is often employed in cold drawing, welding, and the general production of metal products. The primary advantages of low-carbon steel lie in its ease of machining, good forgeability, and weldability, making it practical for applications that require deformation, shaping, or welding.
