| description | The invention relates to the technical field of pipeline steel, in particular to X80 pipeline steel with low-temperature toughness. The X80 pipeline steel comprises the following chemical components: C, Mn, S, P, Si, Nb, Ti, Mo, Cu, Ni, Cr, and limiting elements including B, Ca, N and O, with the balance being iron and inevitable impurities. The X80 pipeline steel with the low-temperature toughness is obtained by subjecting a continuous casting billet of the pipeline steel to heating, rough rolling, finish rolling, rapid cooling and coiling. According to the invention, the chemical components of the pipeline steel are optimized, controlled rolling and controlled cooling processes are combined, fine grain strengthening effect is fully played, the low-temperature toughness of the X80 pipeline steel is greatly improved, and the application field of the X80 pipeline steel is widened.
