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.
This article describes current industry practices to catalog features observed after sulfide stress cracking testing. The article also introduces a quantitative criterion to determine the maximum allowable defect size based on fracture mechanics principles.
This post illustrates a state-of-the-art fastener production line.
Is sulfide stress cracking an anodic or a cathodic process? Does hydrogen play a role or is SSC controlled by anodic dissolution? Find out in this post!
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.
