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.
In addition to the automotive 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 automotive 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 automotive metals, like our guaranteed hole-expansion ratio (HER) grades.
New hot-rolled grades:
Docol HR800HER-75
Docol HR800HER-100
Docol HR1500M

Metal coated 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 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.

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