Notes:
1, 60Mn specification: DIA 80-1200mm(forged round bar), 80-1200mm(square bar) Length 3-16 meters
2, 60Mn heat treatment: Quenching,Annealing,Normalizing and Tempering.
3, 60Mn tolerance: 0-+3mm(DIA), 0-+10mm(Length)

60Mn’s strength, elasticity and hardness are all higher. 60Mn has good machinability and poor Cold deformation plasticity and weldability under the condition annealing.60Mn has sensitive and temper brittleness tendency for overheating. 60Mn is suitable for large size spiral spring, leaf-spring. All kinds of round flat spring. Spring ring plate, cold drawn steel wire and spring.
Our company, KUNFENG can produce all sizes of 60Mn forged steel round bar, 60Mn forged square bar, 60Mn forged shafts and 60Mn forged blocks.
