EV Transition — Advanced High-Strength Steel
Hyundai's Ioniq 5, Ioniq 6 and Kia EV6 use advanced high-strength steel (AHSS) grades that are higher-margin products for Hyundai Steel. As Hyundai/Kia's EV mix increases, Hyundai Steel's product mix shifts toward more valuable grades — a structural quality improvement in earnings.

Is Hyundai Steel independent from Hyundai Motor?
Separately listed but part of the Hyundai Motor Group chaebol. Intra-group steel supply to Hyundai and Kia provides a structural demand floor while external customers add cyclicality.
How does EV production affect Hyundai Steel?
EV models use AHSS grades that are higher-margin for Hyundai Steel. As Hyundai/Kia's EV mix increases, Hyundai Steel's product mix improves in quality and margin.
What is an electric arc furnace?
An EAF melts steel scrap using electric arcs rather than coke in a blast furnace — significantly lower CO2 emissions. Hyundai Steel's EAF capacity positions it ahead on green steel metrics.
