Steel has always met important needs in society, bettering people’s lives. The same is true as the world undergoes essential shifts to meet climate-related goals. Within the clean energy transition, steel has found its way into the most critical technologies. Sustainable steel products are essential to lowering GHG emissions, and underpin the development of green technologies. They enable and support vehicle electrification, energy transmission and renewable-energy infrastructure, among many other important roles.
At U. S. Steel, we are meeting our customers’ continued need to develop lighter and stronger steels, while utilizing lower-emissions technology, by creating the steels of tomorrow with the same tenacity and adaptability that has brought our steel solutions to life for more than 100 years. Our customers trust our highly skilled talent and advanced capabilities to create innovative products and specialty solutions for their ongoing and emerging requirements.
One way we demonstrate our commitment to sustainability is through our Life Cycle Assessment/Environmental Product Declarations (EPDs). EPDs support customers and society at large by providing quantifiable, independent, and audited environmental data to customers on the products they purchase. In 2023, customers were offered EPDs for flat-rolled coil products melted at our integrated and mini mill plants in North America. Our three key offerings are hot-rolled, cold-rolled and corrosion-resistant flat-rolled products.
A key sustainable-steel product is non-grain-oriented (NGO) electrical steel, produced by U. S. Steel Košice (USSK) and U. S. Steel’s Big River Steel Works. In 2023, USSK used pilot lines and laboratory simulations to provide technical support to produce these advanced NGO electrical steels and set up new production processes at Big River Steel Works on their new NGO line.
Advanced Products
To meet the needs of today’s important applications, as well as to pave the way for tomorrow’s, we are constantly developing and improving innovative steel products — all mined, melted and made in America. Here are some of those products:
COASTALUME™
Combines USS GALVALUME® with DuPont™ Tedlar® PVF film to produce a maintenance-free and highly sustainable roofing and siding solution, designed to meet the special durability needs of coastal residential and commercial construction.

InduX™
A wide, ultra-thin and light-weight steel, with all the magnetic properties necessary for electric vehicles (EV), as well as generators and transformers. This steel’s optimized magnetic properties increase EV motor efficiency, leading to better mileage. InduX™ is produced on the new NGO electrical steel line at BR1 in Osceola, Arkansas, representing a significant investment in American jobs, and bolstering the resilience of the country’s domestic supply chain.
XG3™
A third-generation hot-dipped galvanized steel for automakers that 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.
