Thyssenkrupp Steel is to start supplying its bluemint CO2-reduced recycled steel to BMW Group during 2026 for use in series production, in particular for the outer panels, interior parts and battery housing of the BMW iX3, Kallanish hears.
The material has a high proportion of recycled material and achieves CO2 savings verified by TÜV Süd compared to conventional steel, the steelmaker says. This is a mass balanced recycled product, involving a mathematical allocation procedure using CO2 reductions from its production process which can be attributed to products on a pro rata basis, the company explains.
BMW Group will use the steel in series production without having to adapt existing processes, tk notes.
The German automotive industry uses almost exclusively primary steel extracted from iron ore for the outer body shell for the highest requirements in terms of surface quality, formability, and processing. This reduced emissions steel can meet these quality requirements and can be used for outer panels, the steelmaker adds.
