Chemical composition and experimental-industrial technology for production of structural steel alloyed economically with nickel of increased cold resistance for promising ice-class gas vessels and storage tanks for liquefied natural gas with operating temperature of -164°C are developed. The prospects of such materials in shipbuilding are shown. The microstructure of cryogenic steel is studied, for example, it is shown that impact toughness at cryogenic temperatures increases with proportion of austenite in the microstructure.
