SMC11T0 is a low alloy Carbon steel OCTG material suitable for severe Sour Service applications while providing enhanced and guaranteed Collapse resistance compared to API ratings. SMC110T is a Sulfide Stress Cracking (SSC) resistant material, which production order is delivered with both SSC and Collapse proof tests.

SMC110T is equivalent to SMC110, produced using the same manufacturing route as SMC110 with additional controls meant to achieve higher collapse resistance.

SMC110T derived from the combination of SMI's unrivaled know-how in mastering both High Collapse and Sour Service technologies, interlocked with best-in-class quality control. SMC110T has no equivalent in API 5CT/ISO 11960 grades and in order to achieve its superior Sour Service properties SMI applies a very strict QA/QC throughout its manufacturing route from Steel Making to Heat Treatment process.
