C45 steel is a widely used medium carbon steel known for its balance of strength, toughness, and machinability. When cold drawn into bright bar form, it gains improved surface finish, dimensional tolerance, and enhanced mechanical properties, making it ideal for use in precision engineering, machinery components, and automotive applications.
At Steelmet Industries, we supply C45 cold drawn bright steel round bars in a wide range of sizes, with the ability to deliver custom lengths, special profiles, and critical quality requirements on request.
