Molybdenum is added to improve elevated temperature strength and corrosion resistance for type 316 compared to type 304 stainless steel. Strong carbide forming elements, like titanium and niobium, are also added to these steels to improve creep strength and reduce stress corrosion cracking, as well as to improve resistance to irradiation induced swelling and helium embrittlement. This work shows that fairly pure TiC and NbC form in Ti- and Nb- stabilized versions of type 304 stainless steel (types 321 and 347, respectively); however, the Ti-rich MC dissolves Mo considerably whereas the NbC remains compositionally quite pure when these phases form in Ti- and Nb- modified type 316 stainless steels, respectively.

Abstract A creep-deformation, heat treatment impact-fracture technique that can be used to produce grain boundary surfaces is described. The technique is especially useful for exposing grain boundaries of austenitic stainless steels and can also be used with surface-sensitive analytical techniques. Intergranular fracture surfaces of Type 304 stainless steel have been produced using this technique. Auger electron spectroscopy analysis was performed on these fracture surfaces.
