Abstract

The effect of second phases and alloying elements on stress corrosion cracking (SCC) behavior of oil well steel T95 in sour H₂S environments was investigated by means of electrochemical polarization measurement, constant tensile test, optical microscope and transmission microscope. Results showed that solutions of pH=2.3 and pH=2.8 were SCC sensitive environment to T95. With the decreasing pH, cracking time of the prestressed rings decreased, namely, the SCC sensitivity of T95 increased. With the decrease of pH, the I_H+ (input current from the environment) increased, while the cathode reaction was enhanced, as a consequence, the hydrogen induced cracking (HIC) occurred. Meanwhile, the aggregation of H⁺ on the crack tip might promote the crack expansion, accordingly, the anodic dissolution was enhanced. The crack propagation was controlled simultaneously by anodic dissolution (AD) and hydrogen embrittlement (HE) in the solutions of pH=2.3 and pH=2.8.

Key words: acid media stress corrosion constant load tensile H₂S crack propagation oil well pipe steel
