Abstract:
Hydrogen is supposed to play an important role for future energy storage and automotive applications. Almost all metallic materials exhibit a degradation of mechanical properties in the presence of gaseous and/or dissolved hydrogen, an effect known as hydrogen induced embrittlement. For hydrogen storage in automotive applications specific problems do not arise for the tank but for tank components like fittings, flanges, tubes etc. These components are usually made of austenitic stainless steels (ASS), for instance AISI 316L, alloyed with comparatively high amounts of nickel to ensure an acceptable level of hydrogen environment embrittlement (HEE). However, high nickel prices are the driving force for the development of lean-alloyed austenitic steels with moderate HEE. In this contribution, computational thermodynamics are applied to the investigation and development of low-nickel ASS in the context of hydrogen embrittlement. The influence of austenite stability is discussed and effects of segregations are highlighted.
