STP 962 Hydrogen Embrittlement: Prevention and Control Louis Raymond, editor

STP 962
Hydrogen Embrittlement:
Prevention and Control
Louis Raymond, editor

A proliferation of test methods relative to hydrogen embrittlement prevention and control has been generated since the publication of Hydrogen Embrittlement Testing, ASTM STP 543. As a result, only one voluntary consensus standard, ASTM Method for Mechanical Hydrogen Embrittlement
Testing of Plating Processes and Aircraft Maintenance (F 519-77), has been generated since that time. Over 30 other standards, either federal, military, international, or industrial,
have incorporated variations on this single test standard to provide some semblance of consistency throughout the industry.
A recent rash of failures due to hydrogen embrittlement, including failures in alloys other than high-strength steels, has caused a revitalized interest in this activity. The need for more standard test methods has never been more apparent. To this end, it was felt that the time had come to put together a symposium bringing in experts throughout the world to provide ASTM with a state-of-the-art review of the technology, its aplalications, and a focus on how to prevent hydrogen embrittlement failures in the future. These failures can be prevented either: (1) by eliminating the sources of hydrogen in the making of alloys (primarily steel); (2) by the manufacturing of hardware; or (3) by the ultimate generation of hydrogen under different environmental conditions generally associated with dissimilar metals producing galvanic couples that are primarily used as sacrificial anodes to prevent corrosion.
