If a plate is Heated uniformly for hot forming, provided that the temp to which the plates are heated for hot forming does not significantly exceed normalizing temps would this plate require anything more to be considered normalized?.

To a large extent it depends on the forming severity -

If you are just doing a radius it is one thing , If you are doing severe forming you might get grain ( of the steel )

refinement (smaller grain size )

one more thing, I was told that an x-ray film that shows all wires but has a density of 1.2 is acceptable per ASME code, i do not see this, i do see in sec V density limmits 1.8 min is there anything in the code that allows acceptance based on wire IQI only?
