Hydrogen embrittlement relief after plating for alloy parts
I have a question about hydrogen embrittlement relief of electro or electroless plating.
According to the following paragraphs of each specifications, hydrogen relief baking is required only for "STEEL" or "FERROUS" parts
AMS2424 [affil. link to spec at Techstreet] (Low stress nickel plating) para. 3.3 and 3.4.7.
AMS2404 [affil. link to spec at Techstreet] (Electroless nickel plating) para. 3.3 and 3.4.5.
AMS2406 [affil. link to spec at Techstreet] (Chrome plating) para. 3.3 and 3.4.4.
Also, AMS2759/9 specifies only for "STEEL" parts.
I would like to know in case of Nickel or Cobalt base alloy part, whether it requires baking or not.

You would be wise to check with your customer, if possible. My interpretation would be that it is not required for non-ferrous alloys, and my company would not require it.
