Grain boundary engineering of metastable 204Cu, 301, and 301LN austenitic stainless steels to improve their sensitization resistance

Grain boundary engineering (GBE) of 304 and 316 austenitic stainless steels has been widely researched but studies on other grades of austenitic stainless steels are less common. In this study, application of GBE on metastable austenitic stainless steels 204Cu, 301, and 301LN was assessed. Thermomechanical processing parameters were obtained for each of the tested steel grades by varying cold rolling reduction and annealing temperature, and...
