Product Description
SM110XS is a low alloy High Strength Carbon steel OCTG casing material suitable for severe Sour Service applications. SM110XS is a validated full fledge Sulfide Stress Cracking (SSC) resistant material developed based on SMC110 manufacturing experience.

SSC failure mechanism is a form of Hydrogen embrittlement in combined presence of H2S, water and tensile stresses. NSSMC pioneered the development of a 110 grade material able to resist specific sour service applications in the early 90's, under SMC110 name.
