- kleton 7y agoAbout 0.8%. You could throw in coke after hydrogen smelting, and skip the decarburization step that you'd normally need with coke smelting.
- kragen 7y agoA little, but much less. 2Fe₂O₃ + 3C → 4Fe + 3CO₂ consumes a much larger amount of carbon than the 4% in pig iron or the less than 2% in steel.
