HISC is the Achilles’ heel of duplex and super duplex stainless steels. In this investigation, we demonstrate the detrimental effects of both cold work (swaging) and anisotropic microstructures on HISC resistance. We believe the findings challenge the validity of the present form of DNV-GL RP F112 as a method to reduce HISC risks.
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.
In this article, we investigate the inverse correlation between Volta potentials measured by SKPFM and the observed localized corrosion morphology of NAB.
Hydrogen embrittlement is a common, dangerous, and poorly understood cause of failure in many metal alloys. This article presents a model based on the correlation of mechanical properties to scanning electron microscopy fractography analysis of fracture surfaces in the presence of simultaneously active hydrogen embrittlement micro-mechanisms.
This lecture describes various materials selection and corrosion control strategies for subsea oil and gas production systems. A brief discussion on carbon and low alloy steels as well as corrosion resistance alloys is presented alongside fundamental corrosion concepts.
This posts summarizes the main effects of nickel on the phase transformation of kinetics of low alloy steels.
