The reduced corrosion fatigue performance of a heat treated grade of duplex SAF 2205 stainless steel has been quantified using Wöhler rotating bending fatigue machines. The reduction in fatigue performance has been related to elemental profiles around intergranular and intragranular precipitates and grain boundary segregation measured using EDAX analysis and scanning transmission electron microscopy.
