Carbon steel machined parts are metal parts that are typically made from carbon steel and machined using CNC lathes. The material is primarily an alloy of iron and carbon, and can be categorized into low-carbon steel, medium-carbon steel, and high-carbon steel based on their carbon content.
These materials contain little to no alloying elements (such as manganese, silicon, sulfur, and phosphorus), are low in cost, and have good machinability, making them one of the most commonly used structural materials in mechanical manufacturing.
Low carbon steel (carbon content < 0.25%): such as 1020 steel, has good plasticity and is easy to weld. It is often used to manufacture parts that are not subjected to high stress, such as bolts, bushings, and shift forks.
Medium carbon steel (carbon content 0.25%～0.6%): such as 45# steel (S45C), has good comprehensive mechanical properties after quenching and tempering, and is widely used in key mechanical components such as gears, connecting rods, and spindles.
High carbon steel (carbon content > 0.6%): such as T10 tool steel, has high hardness and good wear resistance, suitable for manufacturing cutting tools and molds, but has poor weldability.
