What wrecks have you been diving on that you get colder because there is some steel around ya?
I don't think it would be colder because of the steel, but if you penetrated the wreck, the water temp inside the wreck might be a little cooler because it's lack of access to ambient light and lower or no current flow. (at least that's what I'd think of it...)
but I doubt that unless you go down to the engine room (no current movement and totally dark) you'd see much of a difference in temp.
