Why Nickel Electroplate has several times the yield strength of annealed nickel

I have some samples of nickel electroplate, removed from a coated mandrel. Tensile yield strength is several times the published values for annealed nickel, leading me to wonder if the plating contains hydrogen. Does anyone have any data? Or an alternate explanation of the high YS?

Yes indeed, it has H in it plus other impurities which are responsible for its different microstructure, YS and hardness.
