Abstract Scope |
AISI 347 stainless steel has many beneficial properties including general corrosion resistance and weldability, so it is widely used in industrial applications including as pressure vessels and for chemical processing equipment. It has been used for some nuclear applications, but there is limited experience with low temperature (<100°C) neutron irradiation behavior. Alloy 347 from three suppliers was compared as base metal, tungsten inert gas welded, and flux cored arc welded. The three suppliers’ materials had different grain sizes and impurity content. For the welded materials, samples were cut to either focus on the fusion zone or the heat affected region. Base metal and welded samples were irradiated in the High Flux Isotope Reactor to fluences of approximately 0.08 and 0.8 dpa at the ambient coolant temperature of approximately 60°C. The effects of the different supplier starting microstructure, welding, and neutron irradiation were evaluated through microstructure analysis, tensile, and Charpy tests. |
