13Cr and Super 13Cr

13% Chromium (13Cr) and Super 13% Chromium (S13Cr) materials to be used in sweet CO2 environments at high temperature
In flow wetted tubulars, OCTG carbon steels are known to suffer from mass loss corrosion in CO2 environments.  Martensitic 13Cr and S13Cr materials are suited to resist such in hospitable conditions including high CO2 pressure with limited H2S content and high temperatures, while providing the most cost effective solution.
Best corrosion resistance
Our proprietary 13Cr and Super 13Cr grades offer the highest corrosion resistance for oil & gas fields under high temperature in sweet environments.
Highest proven performances
Decades of know-how and process control are backed-up by hundreds of corrosion test results.
Cost effective
As an alternative to more costly Duplex and Super Duplex grades, our 13Cr and Super 13Cr offer a long-life, cost-efficient solution.
