The invention provides D-grade sucker rod steel and a production method thereof. The steel comprises the following chemical components in percentage by weight: 0.22 to 0.29 percent of C, less than or equal to 1.03 percent of Cr, 0.90 to 1.60 percent of Mn, 0.21 to 0.37 percent of Si, 0.04 to 0.12 percent of V, 0.015 to 0.050 percent of Alt and the balance of Fe and unavoidable impurities. The method solves the problem that the product of the traditional D-grade sucker rod steel which is mainly made of expensive alloy steel or high-component alloy steel has high production and application cost. The D-grade sucker rod steel is produced by processing in a converter and performing continuous casting and rolling and solves the problems of high energy consumption, complex production process and instable product quality and processing application process of the traditional electric-furnace cogging and rolling.
