This lecture describes various materials selection and corrosion control strategies for subsea oil and gas production systems. A brief discussion on carbon and low alloy steels as well as corrosion resistance alloys is presented alongside fundamental corrosion concepts.
Corrosion Resistant Alloys
Does tungsten in super duplex stainless steel improve localized corrosion resistance?
In this presentation, the pitting and crevice corrosion resistance of super duplex stainless steels with different tungsten contents was analyzed using various electrochemical techniques.
The work was presented at the 16th Nordic Corrosion Conference.
This blog entry provides the link to download our final NACE CORROSION 2015 publication on the effect of σ-phase precipitation on localized corrosion of super duplex stainless steels.
This article describes the results of a recent NACE MR0175/ ISO 15156 ballot that imposes stringent maximum allowable stress values.
What are the pitting and repassivation potentials? Is there a correlation between these critical potentials and localized corrosion resistance?
What is the localized corrosion resistance of the Nickel alloy 718 (UNS N07718) in oxidizing chloride containing environments like seawater? This articles gives some clues.
