Product Description
SM80XS is a low alloy Carbon steel OCTG material suitable for severe Sour Service applications. SM80XS is a Sulfide Stress Cracking (SSC) resistant material.

SSC failure mechanism is a form of Hydrogen embrittlement in combined presence of H2S, water and tensile stresses. SM80XS benefits from NSSMC's unrivaled know-how in manufacturing sour service materials since the 70's and best-in-class quality control. SM80XS offers a tighter quality control compared to API L80 and is manufactured based on API 5CT/ISO 11960 PSL2 requirements.
