-----Decorative Chrome Plating fails after Baking at 700 °F
We are currently running a part for customer that is plated with nickel chrome.
The parts will be crimped onto a cup in the final assembly. The end user has specified for these parts to baked at 700F in a nitrogen furnace to prevent cracking. After baking some of the parts have exhibit the plating separating from the base material. What would be the max temperature these parts could be at and not destroy the plating?

First off, what decorative chrome piece needs 700F?
I have never heard of anyone giving any type of thermo testing that reaches 700 °F.
Wow!

Though I understand Mr. Coffie's point, many times I've heated a good quality screw driver or a similar hand tool that is nickel+chrome plated directly to the flame in a stove and I don't recall to have seen the plating peel or bubble. If ppoperly done, nickel+chrome over steel must not peel or destroy. Of course, if the specification calls for such heat treatment, the base metal and its surface will have to be prepared accordingly.
