Abstract
The invention discloses an alloy steel forged steel round bar for a heavy-duty gear, solves the problems of a large deformation rate and poor mechanical property of carburizing and quenching and relates to the field of alloy. The alloy steel forged steel round bar is prepared from the ingredients in mass percent: 0.33 to 0.38% of C, 0.55 to 0.80% of Mn, 0.15 to 0.35% of Si, smaller than or equal to 0.015% of P, smaller than or equal to 0.015% of S, 1.50 to 1.70% of Cr, 1.50 to 1.70% of Ni, 0.23 to 0.30% of Mo, 0.020 to 0.040% of Al, smaller than or equal to 0.20% of Cu, smaller than or equal to 0.05% of V and the balance of Fe and unavoidable impurities. The alloy steel forged steel round bar has a small deformation rate in carbonizing and quenching, the mechanical property is stronger, and the alloy steel forged steel round bar is suitable for producing gears; furthermore, the preparation method of the alloy steel forged steel round bar is more convenient and more suitable for scale production.
