POSCO accelerates low-carbon steel transition with Korea’s largest electric arc furnace
POSCO has completed construction of Korea’s largest electric arc furnace (EAF) at its steelworks in Gwangyang, South Jeolla Province with an annual production capacity of 2.5 million tons, marking a major step in its transition toward low-carbon steel production.

It was built with about 600 billion won ($392.6 million) in investment, with a cumulative 270,000 workers involved.
