This investigation demonstrated 2.1 wt% tungsten drastically reduced the kinetics of tertiary phase precipitation in 25Cr super duplex stainless steels. The slow kinetics resulted in a better overall pitting corrosion resistance.
In this article, we discuss materials and corrosion research topics that could have a transformative effect on the business. In particular, we discuss how scientists and engineers could push the boundaries of existing technologies, learning from the experience gained by other industries such as the nuclear, aerospace, and defense sectors.
Can we use Galvele’s critical acidification model to estimate the localized corrosion resistance of engineering stainless steels?
Short answer: yes; long answer: it is complicated.

Are all super duplex stainless steels alike? Does tungsten additions have an influence on localized corrosion resistance?
Spoiler: it does, and it is remarkable.
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.
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.
