    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

    Available steel grades

    Martensitic (M) steels

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

        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.

            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.

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

                    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).

                            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-Bainite

                                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.

                                    Tubes

                                    Docol Tubes offer the market´s greatest strength range. The tensile strength range starts from 600 MPa and goes up to an extraordinary 1000 MPa without any post-heat treatments. With coating options including zinc, galfan and galvannealed, corrosion resistance and superior paint adhesion can be combined for the first time in high-strength precision tubing. Docol Tubes are made in compliance with standard EN 10305 (parts 3 and 5) with the more demanding elongation values and chemical analyses. To meet the highest customer expectations, we manufacture the tubes with narrow tolerances.
