Corus Steel has launched Dual Phase (DP) 800HyPerform advanced high-strength steel for the automotive market.

It has been specifically developed for use in making lightweight automotive parts such as structural members and reinforcements that must be highly crash-resistant.

The steels’ minimum ultimate tensile strength is 780 MPa, similar to that of Corus’s existing DP800 grade. The difference is that DP800HyPerform offers extra ductility, resulting in good formability in combination with good weldability.

This makes it suited for complex shaped stamped parts. It is available as hot dipped galvanised material and fulfils all typical automotive processing requirements.

It said DP800HyPerform combines the strength levels of a DP800 grade with the formability properties of a DP600 grade, without compromising on weldability.

This grade was developed in close cooperation with a number of automotive OEMs to meet their needs.

The improved formability of the steel results in higher processing yield and enables part consolidation, allowing for smarter and lighter design of crash and structural members.

DP800HyPerform is a Dual Phase steel with improved formability, and is a compromise between the standard DP800 steels and Trip steels in terms of forming properties.

It is easily weldable (similar to DP welding behaviour) and less expensive than Trip steels.
