The reclanation of improperly cadmium electroplated high strength steel parts

Circumferentially notched round specimens of 4340 type steel have been plated in a galvanic bath known to be embrittling. The specimens were reclaimed by stripping and baking. Half the specimens were replated in a non-embrittling bath. Reclamation did not remove all traces of hydrogen embrittlement, but raised the threshold stress to such a...
