The stress corrosion cracking (SCC) behavior of API 5L-X52 low carbon steel has been studied in a presence of different soil solutions, including synthetic NS4 solutions, with and without barrier coatings using slow strain rate tests (SSRT). The coatings used were a multiple layer system (polyethylene, asphalt resin and epoxy resin) and FBE (fusion bonding epoxy). Results from this study indicate that API 5L-X52 is not susceptible to SCC in soils and NS4 solutions at open corrosion potentials when the FBE and the three layer (3-L) coating were used. However, there is some indication of embrittlement and shows susceptibility at - 1.0 V vs. SCE applied potentials with for the 3-L system in NS4 soil solution and FBE in both environment.
