The process of re chroming or indeed chrome plating can cause hydrogen embrittlement. Any process that increases hydrogen at the surface of a metal weakens the metal and can lead to premature failure. The process of increasing nitrogen at the surface toughen the metal (nitriding) I think hydrogen embrittlement can happen to a range of "ordinary" steels which would include a cast steel crank.
