The development of modern steels for large-diameter gas pipelines with stringent requirements for strength properties, resilience, resistance to brittle failure, and weldability is addressed. This paper examines the results of studies conducted on the development of domestic economically alloyed low-pearlite steels for large-diameter gas pipelines intended for service in the far north. The effect of microalloying on strength and plasticity is examined. The chemical composition of the steels under investiation with a different content of carbonitride-forming elements (vanadium, niobium, and titanium) introduced separately and as a group into the melt, as well as aluminum is presented. It is shown that the positive effect of vanadium, niobium, and titanium additives can be realized most fully in low-pearlite steels subjected to controlling rolling.
