| Abstract: |
| Main failure modes and application limit of low alloy steel oil country tubular goods (OCTG) for sour service by relevant international standard were analyzed in this paper. The influences of metallurgical and environmental factors upon sulfide stress cracking(SSC) resistance property were discussed, and selection of SSC evaluation methods were described from the point of stress analysis and fitting for service. |
| Key words: low alloy steel sulfur resistance oil country tubular goods (OCTG) material selection SSC |
