Effects of environmental factors such as H2S partial pressure,PH, Cl
concentration and temperature on SSC property of modified 13Cr steels were systematically investigated. Critical H2S partial pressure for SSC is
affected mainly by temperature and chloride concentrate ion, while pH effect was quite small. In mild conditions such as chloride f ee solution at 25 °C, the steels presented the passive state inhibiting hydrogen entry into steel so that no SSC susceptibility was observed. With increase in...
