Electroplated nickel process for PCB printed circuit boards - ONESEINE
Nickel sulfamate (ammonia nickel) nickel sulfamate is widely used as a metallized hole plating and substrate plating on a printed plug contact sheet. The obtained deposited layer has low internal stress, high hardness, and extremely excellent ductility. A stress relief agent is added to the bath and the resulting coating will be slightly stressed.

I also noticed that your chrome to sulfate ratio is around 75:1. A hard chrome solution typically operates at 100:1 - may want to check your product technical data sheet to verify. If this is the case, may need to add Barium Carbonate to decrease the sulfate or increase the chrome concentration to bring the ratio up to 100:1.

NICKEL PLATING HANDBOOK - Nickel Institute
When current flows, the positive ions react with two electrons and are converted to metallic nickel at the cathode surface. At the anode, metallic nickel is dissolved to form divalent, pos- itively charged ions which enter the solution. The nickel ions discharged at the cathode are thus replenished by those formed at the anode. Rate of Deposition
