Notes:
1, 35Mn specification: DIA 80-1200mm(forged round bar), 80-1200mm(square bar) Length 3-16 meters
2, 35Mn heat treatment: Quenching,Annealing,Normalizing and Tempering.
3, 35Mn tolerance: 0-+3mm(DIA), 0-+10mm(Length)
The grade 35Mn’s strength and hardenability is higher than 30Mn steel. 35Mn’s cold plastic deformation is medium and 35Mn has good machinability but Poor weldability. 35Mn should be used after tempering treatment.35Mn is suitable for rotor,bolt, nut,screw etc,the spindle and the gear.35Mn is used in the manufacture of medium-sized machinery in bolt, nut, leverage, etc.
Our company, KUNFENG can produce all sizes of 35Mn forged steel round bar, 35Mn forged square bar, 35Mn forged shafts and 35Mn forged blocks.
