Are you looking for OEM specific grades?
We develop innovative steel for cars that are often customized for a specific application, in close cooperation with manufacturers. Docol® supplies many steel grades according to VDA and OEM standards. If you don’t find the steel grade you are looking for in below list, send us a note and our technical support will give you more information.
Metal coating
Metal coated Docol® AHSS steels are advanced high-strength steels that are hot-dip metal coated for corrosion protection. Using metal coated Docol® AHSS in structural and safety parts provides lightweight vehicles without compromising passenger safety and corrosion resistance.
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.

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.Docol® PHS steel product offer:

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.Docol® Complex phase steel product offer:

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).Docol® dual phase steel product offer:

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.Docol® High Strength Low Alloy steel product offer:

Ferrite-Bainitic (FB) steels
Ferrite-Bainitic (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.
At SSAB we run projects for these steels to meet the needs on the automotive market. Contact us for more information!
