| Abstract: | Based on corrosion principle of wet H2S,wet H2S corrosion environments are divided into two kinds of corrosion services,sulfide stress cracking(SSCC) and hydrogen induced cracking(HIC).In this article,the conditions and mechanisms for these two corrosions were proposed,and the factors of material and environment to the corrosions were discussed.Finally,the concrete requirements for selected material used in these two wet H2S environments were proposed. |
