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.

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.
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.

Localized corrosion risk assessment using Markov analysis
The objective of this work was to develop the foundation for an interactive corrosion risk management tool, based on Markov Analysis, for assessing the probability of failure of industrial components as a function of threats (such as pitting corrosion and coating degradation) and mitigation schemes (such as inhibitors and coatings). doi: 10.5006/1184
