Recent understanding of the hydrogen influence of medium strength steels

    [abstract] Research on the influence of hydrogen is an ongoing topic for the last 20 years. We developed the Linearly Increasing Stress Test （LIST） that has significant advantages over other testing approaches. Our recent work has studies （i） a range of steels with different chemistries and strengths, （ii） provided an unnderstanding of the relationship of chathodic hydrogen charging to the equivalent gas phase hydrogen ncharging conditions. The talk will provide an overview of our recent work. This research has been motivated by the search for a safe steel for use in the hydrogen economy. There are also applications in oil & gas, in the use of ahvanced high strength steels for auto construction, and in any situation where medium or high strength steels are exposed to a hydrogen environment, which may simply be humid air for the high strength steels, or service corrosion for auto construction.
