Typical nitriding goes down about .015". The greatest hardness is close to the surface..........within .005"..........it falls off as you go deeper..........finally reaching the hardness of the parent metal at about .015".
It's possible to nitride to lesser or greater depths.........depending on how much time is spent in the furnace.
