S20C S45C Steel Round Bars

S20C and S45C are both types of carbon steel that are often used in the manufacturing of machine parts, tools, and industrial equipment. They have similar properties and characteristics, including high tensile strength and good machinability, making them popular choices in the industrial sector.

S20C steel is a low carbon steel alloy that has a carbon content of around 0.20%. It has good weldability, machinability, and ductility, making it ideal for use in the production of shafts, gears, and other machine parts. S20C steel is also known for its excellent toughness and resistance to fatigue, making it suitable for use in high-stress applications.

S45C steel, on the other hand, is a medium carbon steel alloy with a carbon content of around 0.45%. It is often used in the manufacturing of tools, machine parts, and industrial equipment that require high strength and toughness. S45C steel also has good weldability and machinability, although it can be difficult to forge and harden.

Both S20C and S45C steel are available in round bar form, which is used in a variety of industrial applications. These round bars are typically made from hot-rolled steel and are available in various diameters and lengths. They can be cut to size and machined to meet specific requirements, depending on the application.
