In this paper, mechanical properties of type CF-3M cast austenitic stainless steels (CASSs) aged at 548–673K for up to 30000 h were investigated using hardness test and elastic-plastic fracture toughness test in order to evaluate the thermal aging behavior. Moreover, the fracture toughness values obtained by fracture toughness test were compared with the predicted values by H3T model which is one of the fracture toughness prediction method for CASS. As a result, it was suggested that the H3T model was applicable to type CF-3M CASS.
