Material Selection Chart

The Material selection chart provides a simplified guideline to choose from the material applications based on CO2 content, H2S content and temperature.


This material selection chart features NSSMC proprietary grades. NSSMC also does manufacture API 5CT / ISO 11960 grades. For more information, please click here.


Reliable and optimized material selection depends upon a large set of parameters, from fluid characteristics to well conditions. The above chart provides a quick way to make a pre-selection of material type. It should be used as a guideline. For a more detailed assessment, please refer to each Material Data Sheet or Contact Us.
