The present study is a continuation of on the resistance to corrosion cracking and intercrystallite corrosion in welded joints in 12Kh18N10% steel. It has been shown that these forms of damage are sensitive to hot chloride and alkaline solutions and to NACE hydrogenating solution when the welded joints have sensitized heat-affected zones (HAZ), as used in parts of industrial chemical plant, where the intercrystallite corrosion in the HAZ is affected by the working medium, which contains sulfur and also chlorides and hydrogen sulfide at 125{degrees}C. Corrosion cracking resistance was examined in chloride, alkaline, and hydrogen-sulfide environments for welded joints. 5 refs., 2 figs., 3 tabs.
