Description:
"The U.S. Bureau of Mines conducted research to determine suitable construction materials for use in brine and steam environments produced from high-salinity geothermal brines. The high-temperature, high-salinity geothermal brines in the Salton Sea Known Geothermal Resources Area (KGRA) are a valuable source of energy and mineral values. The brine and steam produced from them are corrosive and cause early failure of many common materials of construction. Mass-loss and electrochemical corrosion measurements were conducted on over 60 metal alloys in brine and steam environments produced from geothermal well Magmamax No. 1, located at the Salton Sea KGRA, at temperatures from 180 to 215 deg C, and in synthetic Magmamax brine at 105 and 232 deg C. General corrosion, crevice and pitting corrosion, and stress corrosion were examined along with the effects of dissolved gases. The alloys with the most acceptable corrosion performance in high-temperature, high-salinity geothermal environments were the high-chromium ferritic stainless steels, the inconels and hastelloys, and the titanium alloys. Specific alloys that performed well in wellhead brine included Fe29Cr4Mo, e-brite 26-1, stabilized Fe26Cr1Mo, 6x, inconel 625, hastelloy c-276, hastelloy s, hastelloy g, Ti50a, Ti0.2Pd, and TiCoDe 12." - NIOSHTIC-2
