INNOVATION

CUSTOMER CENTERED.
FUTURE FOCUSED.

U. S. Steel’s Research and Technology Center is where industry-leading expertise and state-of-art laboratory facilities join with customers to advance the science of steel. Here, we discover, test and process-engineer the world’s next generation of steel products and applications.

U. S. Steel customers have long recognized our company as an industry leader and valued partner in the production of high-value-added steel sheet and tubular products. Our solutions are highly sought after by manufacturers in the automotive, appliance, construction, container, and oil and gas industries. Our research organization has been a key factor in both customer and U. S. Steel success—research and technology excellence in steel products and processes is the foundation of a bright future for us, our customers and the world.

The people of U. S. Steel’s research organization are passionate about developing new steels and manufacturing processes for tomorrow’s applications. We provide world-class support to the company’s operations around the world, and collaborate with customers to meet evolving market needs with cutting-edge solutions.

ZMAG™: In 2024, U. S. Steel introduced ZMAG™ steel, an exciting new coated carbon flat rolled steel product featuring a unique zinc-aluminummagnesium coating. ZMAG™ steel is engineered to be strong, more resilient and more sustainable than products on the market today, and with a 25-year warranty, it is ideal for the demands of the domestic solar industry. ZMAG™ steel’s innovation brings a level of corrosion resistance that allows withstanding decades of harsh weather across most U.S. climate zones, unlocking new applications of domestic steel to meet evolving industry needs. The extended life of the product enables customers to meet their material use and life cycle goals and can offset CO2 emissions by delaying the need for replacement. And because the ZMAG™ coating is lighter than conventional coatings, it is produced with lower CO2 emissions.

XG3™: A third-generation hot-dipped galvanized steel for automakers, XG3™ offers a unique balance of high strength and high ductility. XG3™ products are in volume production for our automotive customers, helping them to achieve their weight-reduction and performance goals. XG3™ grades, available in strength levels from 780 to 980 megapascals (Mpa) from our newest line at PRO-TEC Coating Company, are an important part of U. S. Steel’s broad portfolio of Advanced High-Strength Steel products. By enabling weight reduction, XG3™ helps our automotive customers meet their goals for reducing GHG emissions in their vehicles.

COASTALUME™: We combined our GALVALUME® with DuPont™ Tedlar® polyvinyl fluoride (PVF) film to produce a maintenance-free and highly sustainable roofing and siding solution, designed to meet the special durability needs of residential and commercial construction projects subject to harsh coastal conditions. COASTALUME™ offers as much as a 73% reduction in carbon footprint compared to a comparable aluminum roof.

BIG RIVER STEEL: A HISTORY OF FIRSTS

The world’s first Flex Mill®, designed from the ground up to optimize the flexibility, agility and capabilities of mini mill steel technology. One of the world’s first LEED-certified steel mills, reflecting a leader’s commitment to sustainable steelmaking. The first steel mill in North America to combine an electric arc furnace with a Ruhrstahl Heraeus (RH) degasser for cleaner, more formable steels. Big River Steel's history of firsts brings mini mill excellence to U. S. Steel, along with an innovator’s question-everything mentality that fits perfectly with our 120+ years of experience and insight.

Combining Big River's mini mill leadership with U. S. Steel's industry-best steel finishing expands the horizon for a new round of firsts, starting with verdeX® sustainable steels.

InduX™: This wide, ultra-thin and lightweight steel offers all the magnetic properties necessary for electric vehicles (EVs), as well as for generators and transformers. These optimized magnetic properties increase EV motor efficiency, leading to better mileage and range. InduX™ is produced on the new non-grain-oriented (NGO) electrical steel line at U. S. Steel’s Big River Steel in Osceola, Arkansas, representing a significant investment in American jobs and bolstering the resilience of the country’s domestic supply chain.
