Much of what is sold as "cast iron" these days is not made from pure pig iron but contains a significant quantity of scrap metal. This alters the strength and other characteristics of the finished product.
For example when we married nearly fifty years ago my wife and I could only afford a little cast iron hibachi to use for barbequing. It never rusted in all the years we used it. The grills on our current expensive one year old BBQ have nearly rusted through despite being frequently cleaned and treated with cooking oil.
