The sulphide stress corrosion cracking (SSCC) behaviour of UNS G10190 steel in a 5% sodium chloride (NaCl) solution containing hydrogen sulphide (H2S) was studied by slow strain rate tensile testing (SSRT), scanning electron microscopy (SEM), and the electrochemical hydrogen permeation technique. The results revealed different cracking mechanisms and hydrogen permeation currents I-H for UNS G10190 steel sheet in different concentrations of H2S solution. The susceptibility to SSCC of UNS G10190 steel in a 5%NaCl solution containing H2S was evaluated from the permeation current I-H (mu A) which depended on the H2S concentration C (ppm) according to the relationship I-H = 24.5C(0.36). It is shown that the use of all electrochemical hydrogen permeation probe is a practical way to assess susceptibility to SSCC.
