FIELD: metallurgy.
SUBSTANCE: ingot is produced by the method of electroslag remelting from steel, containing in wt %: C 0.025, Cr 22, Ni 10.2, N 0.36, Mn 6.2, Si 0.34, Mo 1.9, sulfur 0.003, P 0.005, Fe - the rest, it is cut into billets, homogenization annealing of the billet in the oven at the temperature of 1100°C for 1 hour and cooling in water are carried out, it is hot rolled at the temperature of 1100°C with a total true degree of deformation of 70% and cooled in water, then it is finally rolled into a sheet of 3-10 mm at temperatures of 950-1075°C with a degree of deformation of 70% with cooling in water.
EFFECT: increasing the index of impact strength at cryogenic temperatures.
