Interactive Effects of Cold Work, Yield Strength, and Temperature on Sulfide Stress Cracking


In an effort to better define the interactions among cold work, yield strength, and temperature with respect to sulfide stress cracking (SSC), a statistically designed experiment was conducted using a 90 grade, sour service, low-alloy tubular steel. The SSC tests were conducted using stressed, notched, bent beam specimens exposed to the National Association of Corrosion Engineers (NACE) solution at various temperatures. The experimental strategy was based on a face-centered cube design, and regression analyses were used for interpretation of the data. Results indicated that the primary influences on SSC were those of yield strength and temperature and that cold work had little effect up to a prestrain of 5%. The threshold stress for a given yield strength was found to change with temperature.
