I'm thinking that factories chromed frames that were of brazed construction, why couldn't you?

Unfortunately I don't know the temperature used in the plating process, where I assume that molten copper, nickel and chromium are electroplated onto the frame. I doubt it would approach the temperatures used in drawing and tempering steel, though. Hopefully a more knowledgeable poster will step in...

Also, the frame probably should be baked after chromeplating to ensure there is no problem with hydrogen embrittlement.
