Hello everybody, The question that I have is: Is there any way to measure the hydrogen level into a steel part that failed already (suspect of H2 embrittlement)? Thanks

[updated:LAST EDITED ON Feb-29-04 AT 11:58 AM (CDT)]Alin: There are chemical analysis techniques for measuring the hydrogen content of a metal or alloy. However, hydrogen will typically diffuse out of the metal when charging stops and your analysis may not be accurate. Hope this helps! David Hendrix The Hendrix Group Inc.

You should better get interest in thermal history, including welding and stress level. If applied stresses are far under mechanical resistance, you ought to consider at least a fatigue failure. if you consider carefully the initiation point of failure, you should be able to know wheter it is fatgue or hydrogen embrittlement
