Abstract

A 2.25Cr-1Mo steel has been creep tested in hydrogen using internally pressured tube testing. A decrease of creep properties in hydrogen was accompanied by microstructural evolution typical of hydrogen attack. A peculiar distribution of damage through the wall of the tube was observed, and is attributed to the particular boundary conditions of stress and hydrogen concentrations, inherent in this type of testing.
