For the first time, long-term strength (the main design characteristic of power generating equipment) of metal of hot-rolled boiler tubes manufactured with various reductions on a tube rolling unit with a continuous mill (TPA 30-102) of INTERPIPE NIKO TUBE LLC from non-deformed continuously cast steel 20 billets of a new manufacturer (MZ DNIPROSTAL LLC) was studied. Structure and fracture pattern were studied in tests for heat-resistance of tube samples in various states (after hot rolling and a
