Carbon steel round bars are cylindrical metal bars made primarily of carbon steel. Carbon steel is an alloy of iron and carbon, with carbon being the principal alloying element. These round bars are widely used in various industrial applications due to their excellent strength, hardness, and machinability. Here are some key points about carbon steel round bars:

Composition: Carbon steel round bars typically contain varying amounts of carbon, depending on the grade and specific requirements. Common grades include low carbon steel (e.g., AISI 1018), medium carbon steel (e.g., AISI 1045), and high carbon steel (e.g., AISI 1095). Other alloying elements such as manganese, sulfur, phosphorus, and silicon may also be present in small amounts.

Manufacturing: Carbon steel round bars are typically produced through hot rolling or cold drawing processes. Hot rolling involves heating the steel billet to high temperatures and passing it through rollers to form the desired shape. Cold drawing, on the other hand, involves pulling the steel through a die to achieve the desired diameter and surface finish.

Sizes and Dimensions: Carbon steel round bars are available in various sizes and dimensions to suit different applications. Common diameters range from a fraction of an inch to several inches, with standard lengths typically ranging from 12 to 20 feet. The surface of the bars can be either smooth or with a textured finish, depending on the manufacturing process and requirements.

Applications: Carbon steel round bars find applications in a wide range of industries, including construction, manufacturing, automotive, machinery, and engineering. They are commonly used to manufacture shafts, axles, gears, bolts, nuts, studs, and other components requiring high strength and durability.

Properties: Carbon steel round bars exhibit excellent mechanical properties, including high tensile strength, hardness, and wear resistance. They can be easily machined, welded, and heat treated to achieve desired properties such as increased hardness or improved ductility.

Finishes: Carbon steel round bars are available in various surface finishes to meet specific application requirements. Common finishes include black (as-rolled), pickled and oiled, cold drawn, turned, and polished.
