Alkaline bath verses Cyanide bath as related to hydrogen embrittlement

Are any adjustments to baking for hydrogen embrittlement required or eliminated when plating parts of 4140 cast steel and heat treated to Rc 41-43 using alkaline versus cyanide baths?

You didn't state what metal you are plating. I'll assume zinc. Baking is the same regardless of the bath type.

NO. There might be a slight difference in the amount, but both process require a bake for the same length of time and temperature.
