A technology of К60-D strength class sheet rolled stock production at 2800 mill of JSC “Ural Steel” elaborated and implemented, by application of thermomechanical rolling followed by accelerated cooling. It was shown that the implemented technology provides the required complex of mechanical properties and high resistance of the rolling stock within a wide dimensional range. The thickness of the rolling stock, produced for trunk pipelines and field oil and gas pipelines, gas-collecting nets pipelines and natural gas liquefaction plants as well as pipelines details was 21.2; 28.5 and up to 45 mm correspondently. Complete meeting the properties of the К60-D strength class sheet rolled stock, produced by the elaborated technology, the requirements to the materials for two-seamed 1420 mm diameter pipes of D category was confirmed by results of tests.
