High chromium-molybdenum iron-base alloys, nickel-base and titanium-base alloys, and a titanium-zirconium-molybdenum alloy (TZM) exhibited good resistance to general, crevice, pitting, and weld corrosion and stress corrosion cracking in laboratory tests in deaerated brines of the Salton Sea known geothermal resource area (KGRA) type at 232°C and in brine containing dissolved carbon dioxide and methane. Only titanium-base alloys were resistant to corrosion in oxygenated Salton Sea KGRA-type brine. Copper adversely affected the resistance to general corrosion of low-alloy steels in deaerated brine, whereas chromium, nickel, silicon, and titanium improved it. Carbon steel, Type 4130 steel, and Types 410 and 430 stainless steels exhibited poor corrosion resistance in field tests in five brine and steam process streams produced from geothermal well Magmamax No. 1. These alloys were highly susceptible to pitting and crevice corrosion. General corrosion rates were high for the carbon and Type 4130 steels.Read More
