The corrosion rate and corrosion attack characteristics were determined for thirteen commercially available materials exposed in a geothermal production well for three months. The materials included carbon steels, Cr-Mo alloy steels, martensitic and ferritic stainless steels, high-nickel alloys, and titanium. The environment at the 1800 ft (600 m) depth of exposure was a single phase high salinity brine. The prevailing temperature was 260{sup 0}C and the prevailing pressure was 630 psi (4.0 MPa) during the exposure period. Results indicated that the carbon steels suffered intense generalized and localized corrosion. Addition of Cr and Mo to steels imparted significant improvement in the corrosion performance in this aggressive environment. Of the stainless steels tested, the most resistant were those containing a few percent molybdenum.
