High-Temperature Corrosion Rates of Several Metals with Hydrogen Sulfide and Sulfur Dioxide
Open accessAbstract
The corrosion rates at temperatures above 1000°K were determined for several metals including copper, silver, Inconel, nickel, 18‐8 stainless steel, iron, tungsten, molybdenum, and tantalum in atmospheres of hydrogen sulfide, sulfur dioxide, and carbon monoxide. This was done by increase in electrical resistance of the metals in the form of filaments 0.010 inch in diameter. The metals most easily corroded in were Inconel, iron, copper, and stainless steel, whereas tungsten, molybdenum, and tantalum offered the most resistance. Inconel is very resistant to , whereas tungsten, tantalum, and molybdenum are easily corroded. Carbon monoxide increases the corrosion rate of nickel in hydrogen sulfide, whereas the corrosion rate of iron is decreased in the presence of carbon monoxide.

Nickel has a low Ni-Ni2S3 eutectic point at 645°C, explaining the high sensitivity of high-nickel materials to sulfides at atmospheric pressure, while chromium and molybdenum increase corrosion resistance toward sulfides.
“Nickel exhibits a low Ni-Ni2S3 eutectic point at 645°C explaining the high sensitivity of high nickel materials to sulfides at atmospheric pressure 67 , while chromium 68 and molybdenum 69 are known to increase corrosion resistance towards sulfides.”
From Continuous Extraction of Black Liquor Salts under Hydrothermal Conditions (2021) · cites this paper as [67]
The Conclusions (page not available) state that nickel and its alloys corrode very readily in H₂S, supporting the high-sensitivity portion of the claim attributed to citation 67. Our copy does not identify a Ni–Ni₂S₃ eutectic at 645°C or give that eutectic as the explanation. The separate chromium and molybdenum claims carry citations 68 and 69, so they are not judged here.

- MODERN ELECTROPLATI NG Second Edition Edited by ALLEN G. GRAY; Assistant Editor, M. LESLIE HOLT Advisory board--William Blum, Charles L Faust, A. Kenneth Graham, Henry B. Linford, Frederick A. Lowenheim, Harold A. Read, Ralph A. Schaefer, and Richard M. Wick. 9 39 contributing authors draw on their years of experience with major industrial organizations to bring you a complete and up-to-date survey of the most recent advances in the science of electroplating. This new second edition is divided into three major parts: section I covers general principles, methods of control, and principles of alloy plating; section II deals with all the major metals from brass to cyanide zinc; and section III treats uncommon metals, plating on aluminum and magne- sium alloys.

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.
