SIMULATING THE SUSCEPTIBILITY TO IGSCC OF COLD WORK 316 AUSTENITIC STAINLESS STEEL EXPOSED TO PRIMARY WATER

摘要

A local model was proposed in the past to better predictthe susceptibility to IGSCC of alloys 600 and 182. Morerecently such an approach was used to simulate EDFoperational experience observed on primary pumps A286studs. The current paper extends the calibration of thelocal model to 316 stainless steels exposed to primarywater. First, the experimental procedure and the resultingmodel are detailed. Second, the model is coupled withdigital tools (Code_Aster and Code_Coriolis) to predictSCC kinetics of laboratory specimens. Finally, simulationsare performed at the scale of components.
