The structure and mechanical properties complex of X80 pipe grade steel after controlled rolling and low-temperature treatment were studied. The microstructure of X80 pipe steel has been studied, the size of the structural components has been determined. The mechanical properties of steel for samples cut perpendicular and parallel to the direction of the rolling axis are determined. Serial curves of impact toughness were constructed and the fracture surfaces of the samples of the steel under investigation were researched.

Keywords: ferrite, controlled rolling, accelerated cooling, bainite, macrostructural analysis, impact toughness, low-temperature annealing
