thyssenkrupp Steel Supplies CO₂-Reduced Steel for BMW iX3 Production

Introduction

Starting in 2026, thyssenkrupp Steel will supply bluemint® Steel, a CO₂-reduced product, for the BMW iX3. This steel will be used in key areas such as outer panels, interior parts, and battery housing.

CO₂ Reduction and Quality

bluemint® Steel incorporates a high proportion of recycled material, achieving CO₂ savings verified by TÜV Süd. It meets the high surface quality requirements for automotive outer body shells, traditionally made from primary steel.

Production Process

The steel is produced using a classic blast furnace route, where part of the iron ore is replaced by specially processed scrap. This reduces coking coal usage and CO₂ emissions without compromising quality.

Application in Battery Housing

In the BMW iX3, bluemint® Steel is also used for battery housing, benefiting from steel's properties like high temperature resistance and electromagnetic shielding, crucial for electric vehicle safety and performance.

Future Plans

thyssenkrupp Steel plans to transition to carbon-neutral steel production by 2045, with a hydrogen-capable direct reduction plant set to produce up to 2.5 million metric tons of direct reduced iron annually, reducing CO₂ emissions by up to 3.5 million metric tons per year.
