Abstract
Damages related to hydrogen absorption in steels are well known and described since decades. As hydrogen sources often moist electrode covering as well as etching and galvanic processes and corrosion are mentioned. In contrast, the hydrogen absorption during heat treatment processes in hydrogenous atmospheres was rarely referred. In the context of this review this hydrogen source will be described and specific cases of damage will be reported. The case of damage always occurred in combination with a missing or unfavorable heat treatment and/or previous material conspicuity. In contrast, the heat treatment processes which were applied in an appropriate way for million times, offer high process reliability without damages caused by hydrogen.
