1020 1045 carbon steel round bars

1020 and 1045 are both common grades of carbon steel used for manufacturing round bars.

1020 carbon steel is a low-carbon steel with a carbon content of approximately 0.20%. It offers good machinability, weldability, and formability. The round bars made from 1020 carbon steel are commonly used in general engineering applications, such as shafts, gears, axles, and other components that require moderate strength and ductility.

1045 carbon steel, on the other hand, is a medium-carbon steel with a carbon content of approximately 0.45%. It provides higher strength and hardness compared to 1020 steel while still maintaining good machinability. Round bars made from 1045 carbon steel are often used in applications requiring higher strength, such as crankshafts, studs, bolts, and machine parts subjected to heavy loads and wear.

Both 1020 and 1045 carbon steel round bars are readily available and widely used in various industries. They can be further heat treated or surface treated to enhance their mechanical properties or improve corrosion resistance. These carbon steel round bars offer an affordable and versatile option for many applications that require reliable strength and machinability.
