Maximize your choice of AHSS/UHSS automotive solutions: Docol® 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.
In addition to the steel grades listed below, SSAB offers hundreds of 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.
We can help at each step: material selection, crash simulations, design optimization, production modeling, effective workflow planning, and tooling recommendations. Plus, you have immediate access to on-demand webinars and articles on key issues such as AHSS simulations, managing springback, and fossil-free steel.
In addition to the open for sales steels listed in the “Available steel grades” tables below, SSAB is constantly developing new 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 steels, like our guaranteed hole-expansion ratio (HER) grades.

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.

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 steels are suitable for applications where high strength, good bendability and stretch-flange ability is required.

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).

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-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.
