Steel grade C60E

Steel grade C60E is a high-carbon, high-strength structural steel for tempering, i.e. quenching and tempering. The E designation indicates reduced sulfur and phosphorus content, which improves structural uniformity and fracture toughness and fatigue resistance.

The high carbon content provides high hardness and wear resistance. After quenching and tempering, the steel achieves a surface hardness in the range of 55-60 HRC (depending on the processing parameters), while maintaining sufficient core ductility, which is crucial for parts exposed to variable loads.

C60E steel is characterized by moderate machinability due to its high carbon content and specific S and P content. Machining, such as turning, milling and drilling, requires tools with high wear resistance and coolant.

Thanks to its properties, C60E steel is widely used in the manufacture of parts requiring high hardness and wear resistance, such as springs, shafts, gears and tools.

C60E steel is susceptible to heat treatment processes, which makes it possible to adapt its properties 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.
