Hertha Metals today broke ground on Hertha Chalyx, its first commercial plant, designed to produce about 10,000 metric tons a year of steel-grade and magnet-grade high-purity iron combined. Built next to Hertha's Pi100 pilot plant, Chalyx forms the first modern iron and steel innovation complex in the U.S., where Hertha will develop and scale its process for making primary iron and steel.

Hertha Metals, the steel company behind the world’s first single-step steel and high-purity iron process for lower-cost domestic production, today announced the close of a $133.65M Series A round, including a $65M equity investment from the U.S. Government, executed through its Industrial Base Analysis and Sustainment (IBAS) program in partnership with the Economic Defense Unit. The round was co-led by Khosla Ventures and Doerr Capital, with participation from CEV, Pear Ventures, Gates Frontier, Niterra SUISO no MORI Fund (General Partner: Global Brain), Toyota Ventures and Siemens Financial Services. IBAS is a federal program that funds projects to strengthen and modernize the defense industrial base.

Hertha Metals, developer of the world's first single-step process for producing steel and high-purity iron at lower cost, has achieved iron production at 99.95% (3N5) purity, meeting the specification required by top rare earth magnet manufacturers. This makes Hertha the first U.S. company to reach this specification with fully domestic inputs, and establishes a domestic source for a material the U.S. currently imports almost entirely. The milestone comes as defense manufacturers face a January 1, 2027 deadline to reduce reliance on Chinese-origin magnets and critical materials, while U.S. industry races to qualify domestic alternatives.

On August 11th, CEO Laureen Meroueh and Hertha Metals – a domestic steel and high-purity iron producing company based out of Conroe – hosted Congressman Morgan Luttrell for a tour of Hertha Metals’ plant. During the tour, Congressman Luttrell saw Hertha’s one-step furnace in action: turning low-grade domestic ore and millscale into high-purity iron for rare earth magnets used in defense, energy, and electronics. The visit also spotlighted Hertha’s upcoming 9,000-tonne-per-year plant, set to bring 550 jobs and strengthen America’s industrial security.

Hertha Metals today announced it has validated a significant technology breakthrough in modern steelmaking: a single-step process that is cheaper, more energy efficient, and just as scalable as conventional methods. The company has been operating a continuous 1 tonne-per-day pilot plant since late 2024.
