Effects of composition and microstructure on oxidation and stress corrosion cracking susceptibility of stainless steel claddings in hydrogenated PWR primary water

•Oxidation and SCC behaviour of 309 L/308 L SS welds were studied in PWR primary water.•There was no indication of SCC for low alloy steel (LAS) after SSRT tests.•The oxidation resistance of 309 L SS was lower than that of 308 L SS.•309 L SS was more susceptible to SCC than 308 L SS in PWR primary w...
