It is used in various applications, including the production of cold heading and rolling screws, nuts, and bolts, as well as in the manufacture of mechanical components such as gears and shafts. In this article, we will explore the properties, applications, and equivalent materials of S20C steel.

What is S20C steel?

S20C steel is a medium-carbon steel with a carbon content of 0.2%. It is classified as a C-series steel, which means it is primarily used for cold forming processes such as heading, rolling, and bending. S20C steel is known for its excellent machinability and weldability, making it a popular choice for various applications in the automotive and manufacturing industries.

Properties of S20C steel

S20C steel has a tensile strength of 600-800 MPa and a yield strength of 300-500 MPa. It has a hardness of 170-200 HB and an elongation of 10-20%. The steel has good machinability and weldability, with a machinability rating of 60-70% and a weldability rating of B.

The steel is suitable for cold heading and rolling applications, with a maximum thickness of 25mm for cold heading and 10mm for cold rolling. It has a minimum bending radius of 1.5 times the thickness of the steel and a minimum twisting radius of 1.5 times the diameter of the steel.

S20C steel is also known for its good wear resistance and fatigue strength, making it suitable for applications such as gears, shafts, and other mechanical components.

Applications of S20C steel

S20C steel is used in various applications in the automotive and manufacturing industries. It is commonly used for the production of cold heading and rolling screws, nuts, and bolts, as well as in the manufacture of mechanical components such as gears and shafts.
