Docol® Automotive Steel Grades

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.

    OEM-specific automotive steels

    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.

    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 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.

    New hot-rolled grades:

    Docol HR800HER-75
    Docol HR800HER-100
    Docol HR1500M
    Docol HR1000CP

    New cold-rolled grades:

    Docol 1900M
    Docol 1700M-EG

    New metal-coated grades:

    Docol CR1180CP-GI
    Docol CR1180DP-GI
    Docol CR1000DH-GI
    Docol HR600FB-GI

    Dual phase with high formability

    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.

        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).

                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.
