Carbon Steel C45 Round Bar Supplier

Home >> Round Bar >> Carbon Steel C45 Round Bar

C45 is a medium carbon steel grade that is widely used in various industrial applications. The “C” in C45 stands for carbon, indicating its carbon content, which typically ranges from 0.42% to 0.50%. This level of carbon provides good strength and hardness properties, making C45 suitable for a variety of mechanical engineering applications.

Carbon Steel C45 round bars are a popular form of C45 steel and are often used in the production of shafts, gears, axles, bolts, studs, and other machine components. These round bars are characterized by their circular cross-section and are available in various diameters to suit different requirements in manufacturing processes.

C45 Carbon Steel Round Bars Applications and Uses

One key advantage of C45 round bars is their excellent machinability. Machinability refers to the ease with which a material can be machined or processed using various cutting tools. C45 steel’s composition and heat treatment contribute to its favorable machinability, making it a preferred choice in applications where precise shaping and finishing are essential.

The heat treatment of C45 steel typically involves processes such as quenching and tempering to achieve the desired combination of hardness and toughness. This heat treatment enhances the mechanical properties of the steel, making it suitable for applications that require a balance of strength and impact resistance.

C45 round bars are often supplied in the normalized or annealed condition. Normalizing involves heating the steel to a specific temperature and then allowing it to cool in still air. This process refines the grain structure and improves the mechanical properties of the material. Annealing involves heating the steel and then slowly cooling it to relieve internal stresses and improve machinability.

In industrial applications, C45 round bars are utilized in the construction of machinery, automotive components, agricultural equipment, and other critical parts where a combination of strength, hardness, and machinability is required. Additionally, C45 is a versatile steel grade that finds application in components subjected to varying loads and stresses.
