The invention relates to Q460 level shock resisting steel and a method for producing Q460 level shock resisting steel by using a steekle mill and belongs to the technical field of metal material processing and moulding. The Q460 level shock resisting steel comprises the following components: C, Si, Mn, S, P, Nb, V, Ti, N, Als and the balance of Fe and other impurities. The method comprises the following steps: firstly, after heating a slab and spraying water to dephosphorize, continuously realizing rough rolling and finish rolling on a same double-rack compact steekle mill; feeding the steel plate after finish rolling to a reeling machine to be reeled by rows; and then naturally air-cooling to room temperature to obtain the Q460 level shock resisting steel with high strength and low yield ratio. By adding microalloy elements such as Nb, V and the like, the strength and toughness of the Q460 level shock resisting steel are effectively improved. According to the method for producing the Q460 level shock resisting steel, the potential of a kunming steel double-rack compact steekle mill is fully explored, the variety of strip plates is expanded and the product structure is optimized.
