Effect of Tungsten on the Pitting and Crevice Corrosion Resistance of Type 25Cr Super Duplex Stainless Steels – Publication
Are all super duplex stainless steels alike? Does tungsten additions have an influence on localized corrosion resistance?
Spoiler: it does, and it is remarkable.
Materials Selection and Corrosion Control in Subsea Oil and Gas Production – Lecture
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.
Use of electrochemical techniques to determine localized corrosion resistance of 25% Cr Super Duplex Stainless Steels: effect of tungsten — Presentation
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.
