Effect of Interstitial Elements on Pitting and Intercrystalline Corrosion of Austenitic Chromium-Nickel Steel

—The possibility of improving the resistance of austenitic chromium-nickel steel of 09Kh18N9 and 08Kh16N11М3 grades to pitting and intercrystalline corrosion under the conditions of standby mode of a fast neutron reactor facility has been investigated. Corrosion tests lasting up to 15 000 h have dem...

Zusammenfassung:	—The possibility of improving the resistance of austenitic chromium-nickel steel of 09Kh18N9 and 08Kh16N11М3 grades to pitting and intercrystalline corrosion under the conditions of standby mode of a fast neutron reactor facility has been investigated. Corrosion tests lasting up to 15 000 h have demonstrated that the corrosion rate decreases significantly upon the decrease in the carbon content and the increase in the nitrogen content.
