Yup. Hydrogen embrittlement, it’s a thing. Look it up!I'm told that the chroming process can make things brittle. Not a big deal, probably, when it comes to blinging up your engine compartment, but you don't want your suspension stuck to crack. It's probably unlikely that chroming will make stuff so brittle that it cracks and I've never had any stuff that I chromed break or crack, but they say it's possible.
