    Abstract

    The history of hydrogen-related problems in heavy steel forgings is traced. Hydrogen embrittlement and its manifestation as “fisheyes” and lowered ductility in tension specimens is discussed. Flaking, its occurrence, detection, and control, past and present, is reviewed. Recommendations for hydrogen control in specifications of ASTM Subcommittee A01.06 on Steel Forgings and Billets are presented.
