Depending on the strength of the steel, hydrogen embrittlement, measured as the relative reduction of area of a smooth specimen in monotonic tensile testing, also increases (shown herein). The figure emphasizes the relative reduction of area in hydrogen as a function of ultimate tensile strength of some ferritic steels.
