3.1 Experimental details
3.1.1 Material and electrochemical environment
3.1.1.1 Introduction to material of investigation
The material chosen for the present investigation was AISI (American Institute of Steel
Institute) type 304L stainless steel. The chemical composition (wt %) of AISI 304L SS is as given
in Table. 3.1. The alloy investigated was used for the construction of a demonstration spent
nuclear fuel reprocessing plant. To get a uniform metallurgical microstructure the as received alloy
was given solution annealing heat treatment at 1050 °C for 30 minutes.
