Abstract

The role of pH value and H₂S concentration on the sulfide stress corrosion cracking of API 2205 duplex stainless steel was studied by means of slow strain-rate tests, polarization curve measurements and surface analysis. It was found that 2205 duplex stainless steel was highly susceptible to sulfide stress corrosion cracking as pH decreased and H₂S concentration increased. When the pH value was 2.8, the susceptibility stayed at a low level in 500 ppm H₂S concentration but there existed a critical H₂S concentration between 500 ppm and 1 000 ppm, above which the susceptibility rapidly increased. The sulfide stress corrosion cracking resulted from hydrogen-induced cracking and exhibited the characteristics of hydrogen embrittlement. The boundary of α phase and γ phase promoted the initiation of stress corrosion cracking, while γ phase inhibited its propagation.
