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.
Are all super duplex stainless steels alike? Does tungsten additions have an influence on localized corrosion resistance?
Spoiler: it does, and it is remarkable.
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.
The deadline for abstract submission is May 1st. This post describes the symposium objectives and provides a link to NACE International Abstract Submission Portal.
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
