Overview

Ferrite-bainite – HR FB590-UC

HR FB590-UC is a ferrite-bainite advanced high-strength steel offering excellent formability characteristics. It is particularly suited to automotive chassis and suspension applications where a combination of superior strength and fatigue performance is required on relatively complex-shaped parts. HR FB590-UC offers a high hole expansion capacity (HEC) and high tensile strength – ideal for components with a significant amount of edge stretching. The tensile strength levels deliver excellent fatigue resistance as an additional benefit.
 

Relationship with standards

Tata Steel can supply the following hot-rolled advanced and ultra high-strength steel grades:

1. This grade is also widely known as 22MnB5.
 

Applications

  • upper and lower control arms
  • engine sub-frames
  • other chassis and suspension components
  • twist beam rear axles
  • wheels

Strength and ductility

Utilising the superior combination of strength and ductility of Tata Steel’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.
