3Cr
Alternative cost-effective grade to extend life of completion strings in mild sweet environments
In flow wetted tubulars, OCTG carbon steels are known to suffer from mass loss corrosion in CO2 environments. 3% Chromium grades represent an alternative to reduce corrosion rate, at a lower cost than martensitic stainless steels (13Cr).
Cost effective
For less critical operations, the use of 3Cr grades offers an overall cost-effective tubing string, either replacing costly 13Cr grades, or reducing workover frequency of carbon steel completions related to high corrosion rates.
