Chung Eui-sun targets SpaceX with U.S.-made low-carbon steel
Hyundai Motor Group's chair, Chung Eui-sun, aims to supply low-carbon steel from a U.S. mill to companies like SpaceX. The mill, HPLS, is a joint venture with POSCO Group and will produce 2.7 million tons annually, with 1.8 million tons for automotive use. Chung highlighted the mill's potential to reduce carbon emissions by 70% and produce high-quality steel for various applications, including rockets.
