S45C steel is a medium-carbon steel with high strength, good load-bearing capacity, and excellent machinability. With approximately 0.45% carbon content, it can be heat-treated to enhance hardness and strength. This steel is widely used in mechanical processing, shafts, gears, molds, and load-bearing components due to its stable hardness and easy machinability.
Characteristics and Features:
Medium Tensile Strength and Hardness: Harder than low carbon steel but still retains some ductility. Hardness and strength can be improved through heat treatment (quenching and tempering).
Good Machinability: Easily cut, milled, turned, and drilled.
Good Weldability: Can be welded using common methods.
Relatively Good Wear Resistance: Can be improved by surface heat treatment.
Reasonable Cost: A common and economical type of steel.
Prone to Rust: Surface protection measures are necessary.
Corresponding CNC Technology:
CNC Milling: Very suitable for shaping machine parts, molds, fixtures, and other components from S45C steel.
CNC Turning: Used for machining round parts such as shafts, gears, bolts, and other machine components.
CNC Drilling: Precise holes can be easily made.
CNC Grinding: Can be used to achieve high precision and surface finish after other machining processes.
Common Applications:
S45C is widely used to manufacture:
Thanks to its good machinability and moderate strength after heat treatment, S45C is a popular choice for many mechanical applications in CNC machining. However, its susceptibility to rust should be noted, and appropriate protective measures should be taken.
