Hydrogen Embrittlement Relief Specifications


I am looking for a specification to reference Hydrogen Embrittlement Relief. I have looked in QQ-P-416 [link by ed. to spec at Defense Logistics Agency,] and in Mil-C-26074 [link by ed. to spec at TechStreet] (Plating specs. for Cadmium and Electroless Nickel). I was hoping the specs would reference the Hydrogen embrittlement specification but they do not. Is there a Hydrogen embrittlement specification out from the government out there? Any help would be greatly appreciated. Thanks, Chris McCain

Check MIL-N-25027D.

Check ASTM B849 [link by ed. to spec at TechStreet] - "Pre-Treatments of Iron or Steel for Reducing Risk of Hydrogen Embrittlement", and ASTM B850 [link by ed. to spec at TechStreet] - "Post Coating Treatments of Steel for Reducing Risk of Hydrogen Embrittlement"
