Recommended AHSS steels for car applications
Docol® steel grades serve specific design purposes and are chosen by designers for a wide range of applications and used by OEMs and tier suppliers in millions of vehicles around the world.
Structural body parts
Parts such as sill reinforcements and cross-members must have both high-energy absorption capabilities and low weight. Stiffness can be maintained with optimized shape.
Suitable steel grades
Consider Docol® Dual Phase (DP), Martensitic (M) or Press-Hardening steel (PHS) grades.
Chassis
High-strength steels provide chassis with excellent formability and fatigue resistance properties.
Suitable steel grades
Consider Docol® Complex Phase (CP) grades.
Bumpers
AHSS steels provide high-force absorption for bumper reinforcements while achieving major weight reduction.
Suitable steel grades
Consider Docol® Martensitic (M) grades.
Door beams
The high-strength levels of AHSS steel result in major weight reductions when upgrading side impact beams.
Suitable steel grades
Consider Docol® Martensitic (M) grades.
Seating
Car seats provide a critical safety structure for occupants. Advanced high steel steels can be used throughout the seat frame, significantly reducing their weight while meeting or exceeding current safety requirements.
Suitable steel grades
Consider Docol® Martensitic (M), Complex phase (CP) or Dual Phase (DP) grades.
EV battery protection
Electric car batteries are expensive and hazardous if damaged in a crash. They also require underside protection from road debris and an enclosure that contains battery liquids in the event of a collision. Docol AHSS steels can help to ensure the strongest EV battery protection with the lowest possible weight.
Suitable steel grades
Consider Docol® Martensitic (M) grades.

AHSS lightweighting of truck components
For many truckers, lightweighting isn’t so much about fuel efficiency as it is about total cost and freight efficiency: being able to earn higher revenue by hauling more — while staying under the legal weight limits. Some truck components that had been switched from traditional carbon steel to lightweight aluminum, or even carbon-fiber-reinforced polymers (CFRPs), are now good candidates for more economical and durable advanced high strength steels (AHSSs).

With Docol® steel, Shape Corp. has improved body structure components for cars
The basic shape of the car hasn’t changed much in a century, but a lot of evolution has happened to the body structure. Thanks to advanced high-strength steel grades from SSAB, Shape Corp. has been able to improve the body structure components of vehicles, with increased safety and reduced weight as a result.

Meet these new hot-rolled Docol® 800MPa steels
To form or stretch cut edges that are crack-free can be a major challenge when working with advanced-high strength steels (AHSS). To reduce the risk of cracked raised edges, SSAB has introduced two new hot-rolled 800 megapascal steels with extremely high edge ductility.
