FIELD: metallurgy. SUBSTANCE: method for manufacture of rolled products includes melting of steel of definite chemical composition, metal treatment in ladle, tapping, austenization at temperature of 1150-1280 C, prior deformation with reduction of 40-92% and total deformation with reduction of 50-70% and temperature of rolling finish of 680-1050 C. versions of thermal treatment and cooling are offered. EFFECT: higher low-temperature ductility and increased cold resistance with preservation of same strength of metal. 8 cl
