Replace costly and CO2-intensive aluminum and carbon-fiber composites with some of the most CO2-efficient AHSS steels available today — and on track to becoming fossil-free, already in 2026.
About sustainabilityOEM specific
Customized advanced and ultra-high strength steels for your specific automotive applications.
Custom AHSS for automotive OEMsSSAB Zero™ – enabling sustainable performance
SSAB Zero™ is the first commercial steel of its kind. By using recycled steel and fossil-free energy, the fossil carbon emissions are virtually zero, without compromising on performance or quality.
The fossil carbon emissions in SSAB’s production of SSAB Zero™ are less than 0.05 kg CO2e/kg steel in Scope 1 and 2 of the GHG Protocol.
Featured automotive steel grades
Maximize your choice of AHSS/UHSS automotive solutions: SSAB Docol® automotive steel grades include martensitic, press hardening steel, complex phase, high edge ductility, 3rd gen dual phase with high formability and more. SSAB uses pure Swedish iron ore and advanced milling processes to make steels with extremely clean properties and highly consistent formability.

A proven process for developing automotive AHSS steel solutions
AHSS steels for higher crash protection
As you strive to provide higher levels of crash protection for passenger compartments – and all-new intrusion-free structures for EV battery packs – SSAB Docol® can help. For example, we have stimulated scores of AHSS beam designs to find optimized profiles, delivering 2x better crash performance (energy transfer) than square tubes.
Lightweighting with SSAB Docol® automotive steels
What are your lightweighting goals for a specific automotive safety component? 10% to 20% weight reduction? Creating thinner — and lighter — components using higher strength steels is a major reason for AHSS’s yearly growth in the auto industry.
AHSS forming optimized for efficiency and repeatability
From concept, to design, simulation, and validation on your production tools, SSAB Docol® experts are with you for your development process for AHSS components. We’ll help you determine the most efficient forming layout – including optimized die materials, die construction, and coatings – for high production quality and parts repeatability.
Exceptional weldability of SSAB Docol® advanced high strength steels
Achieve strong AHSS welds for increased torsional stiffness and fatigue resistance. We designed even our strongest automotive steels to be used with conventional welding processes, including resistance spot welding, arc, and laser. And we’ll aid in your weld simulations, confirming your proposed AHSS joining processes.
Economical and sustainable AHSS automotive solutions
Alternatives to automotive advanced high-strength steels include aluminum and fiber-reinforced composites: both are much more expensive and CO2-intensive, requiring specialized knowledge and equipment to form properly. Both are also more difficult to recycle than AHSS steels.
On the other hand, AHSS automotive steels have a long history of successful problem-solving in mass-produced cars, delivering improved impact protection, significant weight savings, and improved vehicle performance.
