Bidirectional composite impact plate

Abstract

The invention discloses a bidirectional composite impact plate which comprises a steel plate and an iron plate which are combined with each other, wherein the iron plate is prepared from the following chemical components in percentage by mass: 2.5 to 3.0 percent of C, 0.15 to 0.45 percent of Si, 1.15 to 1.65 percent of Mn, less than or equal to 0.025 percent of P, less than or equal to 0.008 percent of S, less than or equal to 0.04 percent of Nb, less than or equal to 0.20 percent of V, less than or equal to 0.015 percent of Ti, 0.005 to 0.030 percent of Al, less than or equal to 0.020 percent of N, 0.002 to 0.003 percent of O and the balance Fe; and the steel plate is prepared from the following chemical components in percentage by mass: 1.2 to 1.4 percent of C, 0.15 to 0.45 percent of Si, 1.15 to 1.65 percent of Mn, less than or equal to 0.025 percent of P, less than or equal to 0.008 percent of S, less than or equal to 0.04 percent of Nb, less than or equal to 0.020 percent of N, 0.002 to 0.003 percent of O and the balance Fe. According to the bidirectional composite impact plate, due to the combination of steel liquor and iron liquor, the steel layer can meet the requirement on the welding performance, and the iron layer can meet the requirement on wear resistance; and the bidirectional composite impact plate has creativity and practicability.
