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.
