Steel grade C60

Steel grade C60 is a non-alloyed tempering steel characterized by high carbon content, which allows for high mechanical properties after heat treatment such as quenching and then tempering. The increased carbon content compared to other non-alloy steels provides better wear resistance and high strength.

After heat treatment, C60 steel achieves high mechanical properties, making it suitable for the manufacture of components subjected to heavy loads and wear. The content of sulfur and phosphorus can reach a maximum of 0.045%, which does not favorably affect machinability, so the use of tools with high wear resistance and coolant is required for machining.

C60 steel is widely used in the manufacture of components requiring high durability and the ability to bear dynamic loads. It is a versatile steel grade for the engineering, automotive and tooling industries, providing durability and reliability in the most demanding applications.

C60 steel is susceptible to heat treatment processes, allowing its properties to be tailored to specific applications. Heat treatments include:

• Hardening: heating temperature: 820-860°C, cooling in water or oil to achieve high surface hardness.
• Tempering: temperature: 150-200°C to reduce stress and improve fracture toughness.
• Normalizing: temperature: 840-880°C, cooling in air to improve structural uniformity and machinability.
• Surface hardening (optional): used for parts requiring a hard surface while maintaining a ductile core.
