SAE 1060, also known as CK60 in the European DIN 1.0601 designation, is a medium-carbon steel widely used in manufacturing components that require high strength, toughness, and good wear resistance. This steel grade contains around 0.60% carbon, which gives it the ability to harden with heat treatment processes like quenching and tempering. It provides a balance between hardness and ductility, making it suitable for medium-stress applications where strength and durability are critical.
The steel is commonly used in the production of automotive parts, gears, shafts, and other mechanical components. With proper heat treatment, CK60 offers excellent wear resistance and fatigue strength, making it ideal for applications requiring high-performance materials.

Mechanical Properties
Machinability
CK60 steel is relatively easy to machine with standard tools due to its medium-carbon content. It can be drilled, turned, and milled effectively. However, care must be taken to use the appropriate cutting speeds and tools to prevent excessive tool wear, especially when machining at higher hardness levels.

Weldability
CK60 offers good weldability with the proper procedures. Preheating is generally not necessary for sections less than 30 mm thick. However, for thicker sections, it is recommended to preheat the steel to avoid cracking. Low hydrogen electrodes are preferred to prevent weld defects. Post-weld heat treatment may be required for thicker sections to maintain strength and minimize the risk of cracking.
