Docol® Automotive Steel Grades
Maximize your choice of AHSS/UHSS automotive solutions: 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.
OEM-specific automotive steels
In addition to the automotive steel grades listed below, SSAB offers hundreds of SSAB Docol® variations to meet specific VDA, SAE, EN, JIS, and OEM standards. We work in close cooperation with automotive OEMs and Tier 1 suppliers to develop custom AHSS grades that give your designs a competitive edge.

The newest AHSS grades
In addition to the open for sales steels listed in the “Available steel grades” tables below, SSAB is constantly developing new SSAB Docol® grades based on future needs of leading car OEMs and Tier 1 suppliers.
Here’s a list of exciting new AHSS developments. Some are “steel family extensions” — that is, grades now available in new hot-rolled or metal-coated versions. Others are all-new automotive metals, like our guaranteed hole-expansion ratio (HER) grades.
New hot-rolled grades:
SSAB Docol HR800HER-75

SSAB Docol CR1180DP-GI
SSAB Docol CR1000DH-GI
SSAB Docol HR600FB-GI
Available steel grades
Martensitic (M) steels
Martensitic (M) steels have very high yield strength (Re) and an extremely high tensile strength (Rm). SSAB Docol® martensitic steel has good draw ability and good edge stretching properties. It is also good in welding.

*Available upon request.
Dual phase with high formability
Metal coated SSAB Docol® 600DH-GI and 800DH-GI are two of the steel grades now avaliable and more are on the way.
DA special heat treatment producing mainly two-phase structure makes SSAB Docol® 600DH-GI and 800DH-GI suitable where an improved formability is requested compared to conventional dual-phase steel grades with the same tensile strength level.
SSAB Docol 600DH
W: Up to 1400 mm
SSAB Docol 800DH
W: Up to 1400 mm
Press Hardening Steel (PHS)
For Press Hardening (PHS) Steel it is the forming process which sets the final characteristics on the material. Forming at high temperatures facilitates complex structures as the martensitic microstructure is developed after press hardening. This material has a limitation in welding properties.
Docol® PHS steel product offer:
SSAB Docol PHS 1800
W: Up to 1500 mm
SSAB Docol PHS 1500
Complex Phase (CP) steels
Complex Phase (CP) steels have higher yield strength and lower work hardening effect, compared to DP steels for same strength level. The CP steels have good fatigue properties when it comes to low cycle fatigue. Compared to DP, the CP steels offer better flanging and ISO hole expansion performance and these automotive metals are suitable for applications where high strength, good bendability and stretch-flange ability is required.
SSAB Docol 600CP
W: Up to 1520 mm
SSAB Docol 1000CP
SSAB Docol 800CP
SSAB Docol 1200CP
W: Up to 1527 mm
*Available upon request.
Dual Phase (DP) steels
For Dual Phase (DP) steels there is a big difference in yield and tensile strength in un-deformed areas. The work hardening in forming is very strong. DP steels have good formability compared to its strength but are limited in hole expansion. With its lean composition these steels are easy to weld but sensitive to heat treatment (> 200 °C).
Docol® dual phase steel product offer:
SSAB Docol 500DP
SSAB Docol 800DP
SSAB Docol 1000DP
*Available upon request.
High Edge Ductility steel for Cars
SSAB Docol® HE is a new range of hot rolled advanced high strength steel (AHSS) with improved edge ductility for automotive manufacturers facing technical challenges in production.
SSAB Docol® High Edge Ductility steel product offer:
SSAB Docol 355HE
W: Up to 1600 mm
SSAB Docol 420HE
W: Up to 1600 mm

High Strength Low Alloy (HSLA) steels
High Strength Low Alloy (HSLA) steels have a typically small difference between yield strength and tensile strength (<100 MPa). They, therefore, offer excellent bendability. With little pearlite and no other hard phases they also have better fine blanking properties compared to DP steels and due to lean composition they are very easy to weld.

Ferrite-Bainitie
Ferrite-Bainite (FB) steels have mechanical properties that are similar to Complex Phase (CP) steels but with a higher gap between yield and tensile strength. FB steels are characterized by good bendability and excellent stretch-flange ability. They are best suited for parts with stretched flanges such as chassis components in cars.
