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.
