Abstract Scope |
Alloy 800H (UNS No. N08810), also known as Incoloy 800 H, offers improved corrosion resistance and high temperature capability over 304/316 grade austenitic stainless steels in a variety of nuclear environments, including light water reactors. This paper reports a comprehensive study of the stress corrosion cracking (SCC) growth behavior of additively manufactured Alloy 800H in 288 C water. Three different heat treatment conditions were evaluated in this study, including stress-relief, hot isostatic pressing followed by solution annealing, and sensitization. These heat treatments present signature microstructural features that will be seen in an actual AM 800H component in service. The in-depth understandings of the unique role of AM microstructure on SCC growth will be discussed in detail, with comparisons to wrought 800H, AM and wrought 316L stainless steel. The effect of sensitization on SCC in AM material will also be revealed. |
