Sensitization Development in Austenitic Stainless Steel — Measurement and Prediction of Thermomechanical History Effects

Abstract

The effects of thermal and thermomechanical treatments on sensitization development in AISI(1) 304 and 316 stainless steels (SSs) have been measured and compared to model predictions. Sensitization development resulting from isothermal, continuous cooling, and pipe welding treatments has been evaluated. An empirically modified, theoretically based model is shown to accurately predict material degree of sensitization (DOS) as expressed by the electrochemical potentiokinetic reactivation (EPR) test after both simple and complex treatments.
