Corrosion of 316L Stainless Steel Alloy and Hastelloy-N Superalloy in Molten Eutectic LiF-NaF-KF Salt and Interaction with Graphite

Influence of microstructure on the corrosion of archaeological iron observed using 3D synchrotron micro-tomography

“…3-a In the presence of graphite, stainless steel has been shown to corrode at double the rate when compared to a system with no graphite present, and forms larger voids in the metal. [56] The initially proposed model of graphitic iron corrosion suggested that the process may only occur if a continuous network of graphite is present in the alloy [47,49] and would not be observed if graphite forms isolated nodules or flakes. The graphite found in the Mary Rose cannon shot investigated in this work does not form a continuous network and occurs instead as isolated flakes.…”

Corrosion of 316H stainless steel in flowing FLiNaK salt

“…Alloy N, developed at ORNL specifically for use as a fluoride salt-facing structural material [25,26], was used extensively in the MSRE [27]. Recent attention has turned to evaluating the compatibility of molten salts with stainless steels [28][29][30][31]. Stainless steels were the subject of some study during the MSRE era as well [5,8,32] with higher mass losses compared to alloy N [9].…”

A non-unified viscoplastic constitutive model based on irreversible thermodynamics and creep-fatigue life prediction for Type 316 stainless

“…316 stainless steel is widespread applicated in pressure-bearing parts in the fields of chemical industry, nuclear power, and aerospace due to its reliable safety and high temperature stability [1][2][3][4][5]. Generally, during the operation of the equipment, the pressure and temperature fluctuation produces cyclic loading which will cause the fatigue damage to the equipment and the inherent stress relaxation during steady operation induces creep deformation [6,7].…”
