- “The U.S. hasn’t built a blast furnace since the 1960s. We offshored steel production...and with it, a core pillar of our industrial strength. Steel is the backbone of everything: buildings, cars, rockets, iPhones, defense. The answer isn’t more massive, dirty blast furnaces. It’s something better. At Hertha Metals, we’re building steelmaking that’s cheaper, cleaner, and less capital-intensive. No coking. No blast furnaces. Just American steel done right!”On the state of US steel production and Hertha Metals' solution. · Aug 12, 2025X
