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.
low alloy steels
Effect of nickel on hydrogen permeation in ferritic/pearlitic low alloy steels – Publication.
This is the first of a series of articles on the effect of nickel on the hydrogen embrittlement resistance of low alloy steels. In this paper, we investigated how nickel in solid solution in the ferrite phase affected hydrogen permeation.
Is sulfide stress cracking an anodic or a cathodic process?
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!
Mechanisms of alternating current induced corrosion of carbon steel – Publication
Does an alternating current or electromagnetic field accelerate corrosion of carbon and low alloy steels? Check our new peer-reviewed article to find out!
Are cracks born from pits?
This article describes the different forms of environmentally assisted cracking that can affect low alloy steels and corrosion resistant alloys in the oil & gas industry.
High strength low alloy steels and hydrogen – Presentation
How can we prevent cracking of high strength low alloy steels when exposed to hydrogen? Take a look at my presentation at the 2015 Robust Materialvalg i Oljeindustrien conference.
