Abstract
An austenitic stainless steel composition is provided that is resistant to embrittlement due to hydrogen and/or low temperature. The steel composition comprises chromium (Cr) at greater than or equal to about 17% by weight; nickel (Ni) at less than or equal to about 13% by weight; nitrogen (N) at greater than 0.16% by weight. The steel is substantially free of molybdenum (Mo). In various embodiments, the steel is used to form a surface of a hydrogen storage vessel that contacts hydrogen and is resistant to hydrogen and low temperature (less than or equal to about -100.degree. C.) embrittlement. Methods of storing hydrogen in vessels made of the hydrogen embrittlement resistant austenitic steel composition are also provided.
