Corrosion Characteristics of Iron-Aluminum And Iron-Chromium-Aluminum Alloys In High Temperature Petroleum Applications^★

This paper reviews the basic metallurgy of the iron-aluminum system and the status of alloy development programs. Published data are summarized dealing with the strength of iron-aluminum alloys at elevated temperature, oxidation resistance, and resistance to oil-ash corrosion. New data are presented on a series of iron-aluminum and iron-aluminum-chromium alloys exposed to various concentrations of hydrogen sulfide at several different temperatures. 6.2.2, 4.3.2, 4.4.2
