Understanding C35K Steel – Properties and Applications

C35K steel is a medium-carbon steel widely used in various industrial applications due to its balanced mechanical properties and excellent machinability. Classified under the EN 10083 standard, C35K is known for its good wear resistance, moderate strength, and ease of heat treatment, making it suitable for manufacturing mechanical components that require durability and toughness.

Chemical Composition and Properties
C35K steel typically contains around 0.32-0.39% carbon, 0.60-0.90% manganese, and trace amounts of silicon, sulfur, and phosphorus. This composition provides the steel with a good combination of strength and ductility. Its tensile strength ranges from 600 to 750 MPa, while its yield strength is approximately 350 MPa, depending on the heat treatment applied.

Applications of C35K Steel
Due to its moderate hardness and machinability, C35K steel is commonly used in the production of:

Gears and shafts

Bolts and fasteners

Automotive components

Machine parts requiring moderate strength and wear resistance

In engineering applications, C35K steel is often heat-treated to enhance its mechanical properties. Processes such as quenching and tempering can improve its hardness and toughness, making it more suitable for demanding conditions.

C35K steel is a versatile material that balances strength, machinability, and cost-effectiveness, making it a preferred choice in mechanical and structural applications. Its ability to undergo various heat treatments allows manufacturers to tailor its properties according to specific engineering requirements.
