    • Abstract


      Delayed failure tests were carried out on hydrogen charged API X-65 grade line-pipe steel in as received (controlled rolled), normalized, and quenched and tempered conditions. The resistance to hydrogen embrittlement was found in the order of controlled rolled $\gt$ quenched and tempered $\gt$ normalized. The fracture mode in the hydrogen embrittled steel was ductile.
