Ferrite grain size and amount of pearlite were Polarization potential measuring apparatus Corrosion Behavior of X70 and X80 Pipeline Steels in change of corrosion rate of X70 steel was not as obvious at high AC density (100-300 A/m2). Under the AC interference with density of 0300 A/m2, the corrosion Microstructure and Mechanical Properties of X70 Pipeline The microstructure of X70 pipeline steel was studied by the analysis of OM, SEM and TEM. The precipitation behavior was discussed. The comprehensive mechanical Effect of grit blasting on the stress corrosion cracking The report describes the results of an evaluation of the stress-corrosion cracking (SCC) resistance of three high-strength, line pipe steels. These steels included PAPER OPEN ACCESS Mechanical Characterization of tensile and impact properties of X70 steels pipeline exposed to wet hydrogen sulphide (H 2S) environments were investigated by Pengyan et al.

  • AbstractIntroductionExperimentalResults and DiscussionAcknowledgmentThe effect of microstructure on the stress-strain behaviour of pipeline steels was studied. Slow strain rate (2×106s1) tests were conducted on grade X65 and X100 steels in silicone oil and hydrogen carbonate/carbonate solution. The as-received grade X100 steel at 75C showed serrated stress-strain curves. The magnitude of the serrations depended upon the strain rate and test temperature. Annealing at 600C or above removes the serrations, but this increased the susceptibility to transgranular crackinMicrostructure and Mechanical Properties of API 5 L X 70 In this study, API 5L X70 steel roll materials welded via submerged arc welding technique (SAW). Macrostructure, microstructure and mechanical properties of welded International Journal of Corrosion - HindawiThe passive films were formed on X70, X80, and X100 pipeline steel in 0.5 mol/L NaHCO 3 solution, which was used to simulate the composition of the high-pH soil.
