Abstract: The combined effect of both creep and hydrogen attack is the object of this study. This is the cause of damage and catastrophic failures of industrial copmonents, with huge economic impact on the affected plants. Tests representative of the industrial reality have been carried out on: the standard 2.25Cr-1Mo steel, the V-modified 2.25 Cr-1Mo steels and the V-modified 3Cr-1Mo. Each of these materials was supplied with an industrial scale weldment. Conclusions on the evolution of the damage and the steps leading to failure are drawn.
