Abstract
The carburization process of heat-exchanger piping of 09Kh18N9 grade steel in contact with sodium coolant under conditions of long-term service at 515°С has been investigated. An effective diffusion coefficient has been determined on the basis of the experimental data on carbon concentration in the metal surface layer; the carburization depth within the temperature range 450–515°С has been calculated.
