Anodic Behavior of Specimens Prepared From a Full-Diameter Alloy 22 Fabricated Mockup Container for Nuclear Waste

摘要

Alloy 22 (N06022) has been extensively tested for general and localized corrosion behavior both in the wrought annealed condition and in the as-welded condition. In general, the specimens for laboratory testing are mostly prepared from flat plates of material. It is important to determine if the process of fabricating a container will affect the corrosion performance of this alloy. Thus, specimens for corrosion testing were prepared directly from a fabricated full-diameter Alloy 22 container. Results show that both the anodic corrosion behavior and the localized corrosion resistance of specimens prepared from a welded container were the same as those from flat welded plates.
