Docol® 600DH dual phase with high formability
General Product Description
SSAB Docol 600DH trip assisted dual-phase steel provides improved formability and comparable weldability to traditional dual-phase steels. Its suitability for car safety and structural components are supported not only by deep drawability but also by enhanced edge formability.
This steel undergoes a special heat treatment producing mainly two-phase structure. Ferrite that imparts unique forming properties represents one phase and martensite that accounts for the strength represents the other phase. Small amounts of bainite and retained austenite improve formability further.

Tolerances
Hot-dip galvanized (GI): Tolerances in accordance to EN 10143.
Customized dimensional and shape tolerances are available upon request.
Coatings
The metal coating options for SSAB Docol products include:
Hot-dip zinc coating (GI) consists almost entirely of zinc (>99%). It is lead free, resulting in a small zinc spangle size. The coating provides good corrosion protection.
Grade specific availability of metal coatings for SSAB Docol products is given in the Mechanical properties table (Coating).
In addition to these coating masses, asymmetric coatings and OEM coating specifications are available upon request.
1) For hot-dipped (GI, ZA, GA) hot rolled (HR) grades, the coating mass tolerance is increased to 30 g/m² by increasing the upper limit.
Surface Treatments
Hot-dip galvanized (GI): available as oiled and/or chemically passivated.
All surface treatments are in accordance with RoHS directive (2011/65/EU) and do not contain Chromium VI (Cr6+). Surface treatments provide only temporary surface protection during transportation and storage. In order to avoid corrosion damages, care must be taken to keep the products dry during transportation and storage. If they become wet, they must be separated and situated so that they are dried quickly.
Fabrication and Other Recommendations
For information concerning fabrication, see SSAB´s brochures on www.ssab.com or consult Tech Support.
Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
