Docol DP and Docol DL are cold reduced dual phase steels. The steels are subjected to special heat treatment in the continuous annealing line, which produces a two-phase structure in which the ferrite that imparts unique forming properties is one of the phases, and martensite that accounts for the strength is the other. The strength increases with increasing proportion of the hard martensite phase.

Docol DP/DL are characterized by a very good formability compared to the strength and also good weldability. All conventional welding methods can be used because of a very lean chemical composition.

Some of the advantages of using Docol DP/DL are:

• Weight reduction

• Simplified manufacturing

• Increased safety

• Improved environment

• Longer lifecycle

• Increased payload

• Increased load capacity

• Reduced total cost

Typical applications for Docol DP/DL are

• Safety components in cars - door beams, bumper reinforcement, seat tracks

• Tube applications - baby rams, furnitures, bicycles
