I have a procedure for the removal of lead coating from Elgiloy wire. It involves using hydrofluoric acid and nitric acid. Is there a concern for hydrogen embrittlement? The material is likely to be made from AMS 5833 which will have about a 46 HRC minimum (no max). NACE MR0175 recommends less than HRC 60 to avoid SSC.
