Abstract
In order to assess the effect of metal sensitization of welded joints of pipelines Du300 from austenitic steel on their service characteristics under the operating conditions of the RP RBMK 1000, samples were tested from steel grade 08Kh18N10T with a constant strain rate from 10–7 to 10–3 s–1 in high water parameters and analysis of changes in their properties.
