Effects of composition on the corrosion of Fe–Ni –Cr alloys in chlorinating and sulfidising environments
Abstract
A series of six austenitic alloys has been prepared in which the nickel content was successively increased from 14 to 78% while retaining a base level of 20%Cr. These were isothermally exposed for 100 hours at 700°C in an air–45% water vapour environment, an oxidising–sulfidising environment (air+49%Ar+26%H2O+1%SO2) and a chlorinating environment at low oxygen partial pressure (argon+0.1%O2+15–26%H2O+0.2–0.35%HCl).The latter two environments gave opposite trends in terms of gross mass change. High metal loss associated with breakaway oxidation occurred at a low nickel contents in the chlorinating environment. In the sulfidising environment the most severe effects were observed at high nickel levels and were associated with the formation of sulfur-containing oxide nodules.

Previous studies have shown that an increased amount of Ni is beneficial for the primary protection and the mitigation of breakaway corrosion.
“Previous studies have shown that an increased amount of Ni is beneficial for the primary protection and the mitigation of breakaway corrosion (see e.g. [5,8,26,37,38]).”

The breakdown of the primary corrosion protection of FeCrNi alloys has previously been studied by several authors.
“The breakdown of the primary corrosion protection of FeCrNi alloys has previously been studied by several authors (see, e.g.[6,9,27,41,42]).”
Peraldi and Pint and R.F.A. Pettersson et al. studied the influence of Ni at higher Ni contents (10-30 wt% Ni and 14-78 % Ni respectively) in the presence of water vapor at 650-800°C.
“Peraldi and Pint [9] and R.F.A. Pettersson et al. [41,42] studied the influence of Ni at higher Ni contents (10-30 wt% Ni and 14-78 % Ni respectively) in presence of water vapor at 650-800 • C.”
Results from both studies indicated that Ni has a beneficial effect on the Cr-rich oxide scale and delayed the formation of a thicker Fe-rich oxide scale also in more complex environments (e.g. in the presence of HCl or SO2).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
