yes, I get that, but is there a definable dividing line? and if not can you say for sure that there IS NOT a dividing line?

Over 2% carbon is cast iron while steel typically is in the .1 to .5 range, but can get up to that 2% line. Wrought iron is roughly .08 and under. I’m not sure of how wide the buffer zone is where one starts to become the other
