EAF steel production accounts for about 30% of global steel production. EAF steelmaking plants tend to be smaller and less expensive than integrated BOF steelmaking plants, which are generally only cost-effective at large scales (millions of tons per year). EAF steelmaking is also a more flexible process, able to scale up and down as the market
