Notes:
1, specification: DIA 80-1200mm(forged round bar), 80-1200mm(square bar) Length 3-16 meters
2, heat treatment: Quenching,Annealing,Normalizing and Tempering.
3, tolerance: 0-+3mm(DIA), 0-+10mm(Length)
has high strength and ’s toughness,wear resistance,static strength and fatigue strength is very good after hardening and tempering. ASTM1330 can be used for important fasteners for small section. can also make the frame longitudinal beam, transmission gear, shaft, cold heading bolt and large cross-section of conditioning.
Our company, KUNFENG can produce all sizes of forged steel round bar, forged square bar, forged shafts and forged blocks.
