The invention discloses automobile beam steel with 960 MPa yield strength and a production method thereof. The automobile beam steel comprises the following chemical components in percent by weight: 0.12-0.14 percent of C, 0.15-0.35 percent of Si, 1.2-1.5 percent of Mn, 0.02-0.04 percent of Nb, 0.3-0.5 percent of Mo, 0.08-0.15 percent of V, 0.01-0.04 percent of Ti, 0.01-0.06 percent of Al, 0.4-0.6 percent of Cr, 0.0015-0.0025 percent of B, less than or equal to 0.02 percent of P, less than or equal to 0.01 percent of S, less than or equal to 0.008 percent of N, and the balance of Fe and inevitable impurities. C and Mn with low content are adopted, the separation strengthening effects of V, Nb and Ti are sufficiently utilized, and besides, a certain amount of Mo, a certain amount of Cr and a certain amount of B are added to control the heat treatment structure state, so that a fine and uniform tempering structure is obtained, the steel has high toughness, high welding performance and high low-temperature impact toughness, the safety performance of a vehicle is improved, the light-weight development of the vehicle is facilitated, and the technical problems that in the prior art, since the low-temperature impact toughness of steel is low, the potential safety hazards of a vehicle are caused, and the lightweight development of the vehicle is limited since the strength of the steel is low.
