We consider specific features of formation of the structure and properties of 03Kh22N5AM3 corrosion-resistant duplex steel in the process of deformation and thermal treatment of rolled milled bars. We analyze the influence of the chemical composition and the conditions of smelting, casting, hot deformation, and heat treatment on the formation of intermetallic phases, which reduce the ductility of the metal. We also give recommendations aimed at increasing the impact toughness of 03Kh22N5AM3 steel at –40 and –46°C.
