Electrical Steel Market

The abundance of iron ore and critical alloying minerals provides a foundational supply-side advantage for electrical steel production, supporting scalability amid rising demand from energy and mobility sectors. The availability of high-quality iron ore will also produce consistently low-impurity steel with superior magnetic properties, resulting in the best-quality iron for grain-oriented and non-grain-oriented electrical steel. Furthermore, access to other key raw materials, such as silicon, will enable precise alloy compositions that reduce core losses and improve electrical resistance. The availability of these resources will stabilize raw material costs, reduce supply chain interruptions, and support large-scale investment in manufacturing. Additionally, because there are mineral reserves in key producing regions, it allows for backward integration to enhance cost competitiveness and increase supply security as the demand for electrical steel continues to grow, resulting from expansion of the grid, development of renewable energy sources, and production of electric vehicles. 

Producing electrical steel is very energy-intensive because it requires specific conditions (ultra-thin-gauge rolling, controlled annealing, and precise magnetic domain refinement) to meet the needs of end-user applications. High temperatures are required for each of these processes, and a stable electric supply is required during the high temperature operations; therefore, electrical steel producers have significant exposure to rising energy costs and increasing carbon pricing mechanisms due to the stringent requirements. Electrical steel has a very limited ability to replace processes without negatively affecting the material's magnetic performance, making it increasingly difficult and expensive for producers to meet required emissions reductions. The high-purity raw materials and specialty coatings used in the manufacturing of electrical steel contribute to CO2 emissions. Consequently, producers are being pressured to invest in low-carbon solutions while producing products that perform as required, resulting in cost pressures and delayed growth in production capacity despite increases in demand from the energy and e-mobility markets.

Expansion into EV-specific non-grain-oriented electrical steel grades presents a strong growth opportunity as automakers increasingly demand materials optimized for high-speed, high-frequency motor performance. These new NGO grades offer lower core losses, higher magnetic flux density, and improved thermal stability under dynamic operating conditions, such as in electric drive systems. As EV platforms continue to develop towards greater power density and more compact motor designs, there is a growing demand for ultra-thin gauges and the highest grades of surface coatings, creating opportunities for steel manufacturers to develop differentiated, application-specific solutions that meet OEM specifications. In addition, the trend toward localizing EV supply chains and the increase in investments to support electric mobility infrastructure provide steel mills with access to new regional markets and create opportunities to develop longer-term contracts, while positioning them as key partners in the electrification of automobiles.

Achieving ultra-low core loss at high frequencies remains a critical challenge in electrical steel development as modern applications such as EV traction motors and high-efficiency generators operate under increasingly demanding electromagnetic conditions. The increased eddy current losses and hysteresis losses at these frequencies mean that producers of electric steel must extremely control the thickness of the material, the grain structure of the material, and the magnetic domain alignment of the material in order to minimize the core loss when producing electric steel at these frequencies. In addition, providing ultra-thin-gauge electric steel without compromising mechanical properties, such as mechanical strength or surface quality, makes the rolling or annealing processes for ultra-thin gauges that much more complex. Also, if the electric steel has advanced coating systems, these systems must provide electrical insulation against the outside while maintaining thermal stability during continuous operation of the electric steel. Due to the requirements of very high precision manufacturing, plus the increased risk of yield, plus the increased cost of manufacturing, it is very difficult for producers of electric steel to produce high performance grades consistently and meet the very stringent expectations for efficiency in automotive and energy industries.
