Round steel bars have high cold deformation plasticity and are generally used in processes such as bending, extrusion, side bending, and arching. It has good welding performance in arc welding and contact welding, and has a lower thickness in gas welding. Workpieces with strict appearance requirements or complex shapes are prone to cracks. The cutting performance of cold drawn or normalized state is better than that of annealed state, so it is generally used for conditions that require low manufacturing force and high toughness.
