Background on the early urgent push for hydrogen control, primarily in heavy rotor forgings, as a result of the rotor failures of the mid 50's, is presented in a brief retrospective. Recent experience with the several degassing processes, their efficiency and costs in terms of safety treatment, delayed deliveries and claim losses is covered. Industry concern with hydrogen analysis of vacuum degassed steel solid product is discussed with regard to end customer need, justification and reliability of analysis, with the increasingly wide-spread use of the ladle refining furnace, some producers are reporting hydrogen problems with low sulfur vacuum degassed steels. Interaction among several factors possibly related to this phenomenon is discussed.
