In your experience, can the plating process be reversed, the stock re cooked, and then replated? If Hydrogen is entrapped, the fissures have already started, and there is possibility for continued embrittlement, post re-plate?
In one description of the failure, there was reference to "Facets" in the degraded areas. This suggests a propagation of fractures at the level shy of inspection at .05 inches?
This is eerily similar to the Shaft problems RR had in the TRENT, perhaps....
