Improvements in steel production technology for main pipelines
A change in the amount of the viscous component was established when testing with a falling load during the aging process of metal that has and has not undergone antiflaking heat treatment. The influence of heat treatment, heating temperature, post-tempering cooling rate, normalization, and annealing on the cold resistance of pipe steel of strength category K60 was studied. The aging of metal that has not undergone antiflaking heat treatment for 33 weeks, as well as an increase in the post-annealing cooling rate, increases cold resistance. The influence of eutectoid transformation on the mobilization processes of atomic hydrogen at the ferrite/cementite interface was characterized. The scientific notation of the theory of hydrogen brittleness has been expanded.
