Bainite frog with excellent toughness and plasticity and preparation method thereof
The invention relates to a bainite frog with excellent toughness and plasticity. The bainite frog comprises the following chemical components in percentage by weight: 0.25 to 0.35 percent of C, 1.0 to 2.0 percent of Si, 1.50 to 2.00 percent of Mn, 0.002 to 0.015 percent of P, 0.002 to 0.010 percent of S, 0.80 to 1.50 percent of Cr, 0.30 to 0.80 percent of Mo, 0.30 to 0.80 percent of Ni, 0.03 to 0.10 percent of V, 0.001 to 0.004 percent of Al and the balance of Fe. In addition, the invention also relates to a preparation method of the bainite frog with excellent toughness and plasticity. According to the technical scheme, the obdurability of the bainite frog is improved, and the running safety of the frog is improved.
