ArcelorMittal is expanding its portfolio in non-grain-oriented electrical steel (NOES). The company is introducing upgraded high-polarisation grades, new self-bonding varnish (SBV) coating solutions, and its latest high-specification low-loss iCARe 420Save grades designed for e-traction applications.
The steelmaker will unveil its new grades at Coiltech Italia 2025, taking place on 17-18 September in Pordenone, northern Italy. The expanded electrical steel portfolio is for industrial applications, with a particular focus on the automotive e-mobility sector, where demand continues to grow rapidly.
“The upcoming launch of our new electrical steels plant at Mardyck in France, alongside our existing Saint-Chély-d’Apcher facility, will significantly increase our electrical steels production capacity,” ArcelorMittal sales director of electrical steels Charlotte Daugu says in a note obtained by Kallanish.
The firm’s latest high-polarisation grades, featuring higher yield strength, have been developed to deliver increased performance and efficiency in the motors and generators industry. ArcelorMittal’s new coating capabilities also include both conventional and rapid self-bonding varnishes.
The next generation of iCARe 420Save grades is scheduled to come onstream in 2026, extending to 0.2mm gauge and combining the lowest magnetic losses with high strength.
The new electrical steel lines at Mardyck will produce 170,000 tonnes/year of NOES, including 145,000t for automotive applications. The facility includes an annealing and pickling line, reversing mill, and annealing and varnishing lines.
In its recent earnings report, the steelmaker said it will postpone the start-up of its Mardyck electrical steel lines from H1 to H2 2025 due to “unforeseen challenges in civil works” (see Kallanish passim).
