A favorable effect is established for reducing carbon and manganese content in low-alloy pipe steels of strength categories X56–X65 on the increase in hydrogen-induced cracking (HIC) resistance of thick-rolled sheet prepared by a thermomechanical treatment regime. This effect is due to a reduction in segregation structural inhomogeneity in the axial area of sheets in the form of a solid band of high-carbon structures.
