Docol Roll
It is a group of high strength cold rolled steels designed for rollforming.
|
Mild Steels
Mild steels spanning the whole range of steel grades intended for relativley simple pressing and bending up to advanced forming with best conceivable properties in both drawing and stretch forming operations. All grades, except Docol Form 07, are adapted to EN 10131.
|
Rephosphorized steels
Phosphorus alloyed high strength steels with good deep drawing properties. The numerical designation indicates the minimum yield strength.

Bake Hardening steels
Bake hardening steels are also rephosphorized steel with good deep drawing properties, but the difference is that the final strength of the finished parts is due to a combination of strain hardening during pressing and bake hardening following painting.

HSLA steels
High strength low alloyed steels intended for pressing. The designation of the steel grades are based on the guaranteed minimum yield strengths.
|
Dual Phase steels
High strength steels with a microstructure that contains ferrite, which is soft and contributes to good formability, and martensite, which is hard and contributes to the strength of the material. These steels are designated according to their lowest tensile strength.
