You will probably find that steel from the crank has also embedded into the fill material in the oil hole.
I see that quite a lot when a bronze bearing/steel shaft is run too hot. The bronze is wiped into the oil grooves, but particles and layers of steel do get embedded in it also. Also steel gets embedded in the bearing surface itself.
