The results of studies on pitting corrosion of 12Cr18Ni10Ti stainless steel austenized after tensile testing at room and low (−20 and −60°C ) temperatures are given. It has been established that local corrosion resistance of cold-deformed stainless steel depends on strain and temperature which determine structure-phase state of material. It is shown that at low degrees of deformation dislocation substructure formed of quasi-homogeneous honeycomb type which has a stabilizing effect on the state of the steel, resulting in increase of resistance to corrosion. Large degree of plastic deformation (>30%) along with the formation processes of high fragmented inhomogeneous structure in 12Cr18Ni10Ti steel initiate phase transformation γ → α΄ to form α΄-martensite, which negatively affects the corrosion resistance of the material.

There were given and analyzed results of physical and mechanical testing of flat samples from Cr18Ni9 (AISI 304) reactor steel which was heat-treated at T=900 °C and 1050 °C and then irradiated with neutrons (WWR-K) to the fluence of 9·1019 n/cm2 and tensile tested at temperatures from 20 to −100 °C followed by magnetization measurements.

The results of the studies of thermal aging effect on corrosion resistance of stainless reactor steel 12Cr18Ni10Ti in unirradiated and neutrons irradiated states have been presented in the paper. The tendency to intergranular corrosion increase with the increase of neutron exposure dose was revealed. A significant reduction in the maximum failure strain and the appearance of the martensite phase was observed during steel testing for corrosion cracking. The maximum content of the martensite phase is formed in the samples aged at 650 °C due to high diffusion mobility of the alloying elements and development of the sensitization process.
