Corrosion tests in geothermal steam contaminated with chlorides, hydrogen sulfide and carbon dioxide are described, detailed results being given for a range of common engineering alloys.
Most engineering alloys proved moderately susceptible to steam corrosion. Titanium and austenitic stainless steels (especially molybdenum-bearing varieties) were highly resistant. Stress-corrosion cracking occurred in hardened 13 Cr stainless steel, hardened low-alloy steels, one grade of austenitic stainless steel and aluminum bronze.
Physical and chemical factors influencing corrosion by the geothermal steam are discussed. 4.6.2
