[Healeys] Chromed parts

Peter, embrittlement occurs to high strength steels when the hydrogen atoms
in the acid solution used in the chroming bath migrate into the crystal
structure of the metal.  If the parts are properly baked according to a
specific time-temperature profile within about 4 hours after chrome plating,
embrittlement is reduced or eliminated.  If the suspension parts were not so
treated after chrome plating, then removing the plating does not affect the
embrittlement.

Gbday again

Ibve been reading the wisdom on chrome plated suspension parts. The general
consensus is bdonbtb. Trouble is, I have some chrome plated steering arms
and drag links that I would like to use (they were on some sort of display
set up) Apparently the problem is bhydrogen embrittlementb caused by the
plating process. Question: does the problem remain if the chrome is removed
either mechanically or chemically?

apologise. Mark b whatbs the solution?
