Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If high-strength flat-rolled
Note (a) yield point specs move to high-strength steel headings.
If forged into blooms
Any worked semi-finished shape leaves primary ingot category.
If plated or coated
Surface treatments constitute 'further worked' per chapter note.
