EN-Automotive-Product-Hot-Rolled-AHSS UHSS- CP800-UC HyperFlange Overview
HR CP800-UC HyperFlange
HR CP800-UC HyperFlange is a complex phase advanced high-strength steel offering freedom in your lightweight design with confident manufacturing. The higher hole expansion capacity (HEC) and elongation give you the freedom to be creative with your design. Its superior edge ductility then gives you the confidence that your designs will not only pass simulations but can also be manufactured reliably. These leads to fewer edge cracks, higher yields, reduced resource losses, and fewer line stops — all contributing to improved productivity and efficiency in your press shop.
Thanks to its outstanding typical HEC of 70% and strong fracture toughness, our CP800 HyperFlange delivers excellent edge ductility. The typical elongation (A50%) is 16%, further enhancing its suitability for a wide range of applications. This product is particularly suited to automotive chassis, ladder frames, suspensions and seating applications. Furthermore, CP800-UC HyperFlange delivers excellent fatigue behaviour, superb cutting-edge quality, improved flatness, good weldability and strong corrosion resistance, thanks to its fine-grained bainitic matrix microstructure combined with a small fraction of ferrite and martensite phases.

Strength and ductility
Utilising the superior combination of strength and ductility of Tata Steel Nederland’s advanced steel portfolio can yield significant lightweighting potential. Component shapes which were previously considered too challenging to make, are now a possibility. This enables designers to integrate high strength and durable materials into their designs to fully unlock the potential of steel.
Increased performance
Application of our advanced steel grades – in place of lower strength, conventional steel grades - can lead to the increased performance of finished components.
Weight reduction
Application of our advanced steel with a lower thickness - in comparison with lower strength, conventional steel grades - can help reduce component weight without compromising performance. This can increase your output per tonne of steel.
Product choice
Our hot-rolled advanced and ultra high-strength steels include ferrite bainite, complex phase and hot forming steel grades.

Shape and dimensional tolerances
The specified values for wide strip do not apply to the uncropped ends of the coil (‘head’ and ‘tail’).
The length of these uncropped ends is calculated using the following formula:
length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.
If required, this part of the coil can be removed, however an additional cost may be charged for this.
