Sulfide stress cracking (SSC) evaluation of high strength OCTG from the view point of environmental factors has been studied to some extent, but little research has been conducted from the view point of fracture mechanics. In the present study, SSC resistance was evaluated using threshold stress and KISSC. The same ranking of SSC resistance is obtained from both methods. However, SSC resistant steels show higher KISSC than conventional steels even if their respective threshold stresses are the same. For steel products bearing cracks and dents, SSC evaluation using both the threshold stress and the KISSC is suggested.
