AbstractThe paper considers the influence of structural heredity on the complex of mechanical properties of shells in the zone of branch pipes from reactor steel in the process of manufacturing the hull of a water-cooled reactor. It is shown that the manifestations of structural heredity have a negative effect in the presence in the shells of primary austenitic grains score No. 3 according to GOST 5639.
Keywordsthe structural heredity, the shell of the nozzle zone, strength, mechanical properties, microstructure, hardening with tempering
