50Mn 60Mn hot rolled carbon steel round bar
50Mn-60Mn high-quality carbon structural steel round bars feature high strength, elasticity, and hardness. 60Mn is particularly suitable for large spiral springs, leaf springs, and wear-resistant parts. It has good machinability but poor weldability and cold deformation plasticity. Commonly used after quenching and tempering.
