Following the successful trials of its XPF product range, Tata Steel has now commercially launched XPF800, a new hot-rolled steel for demanding chassis applications. The new steel offers an unprecedented mix of strength and formability, which gives manufacturers increased design freedom and weight-saving potential, while still being able to create components that guarantee stiffness and fatigue resistance in the chassis system.
XPF800, produced at a tensile strength level of 800MPa, is the first grade of the product family to be commercially available, with XPF650 and XPF1000 in development and to follow. With the recent launch, Tata Steel is the first-to-market in Europe with a hot-rolled product offering high strength combined with exceptional formability characteristics. A hot-dip galvanised range is also in development, which will allow thinner gauges to be used effectively, without running the risk of corrosion that is a concern with thinner steel applications.
The superior formability of XPF800 enables light weighting of complex vehicle components, while achieving the same fatigue performance as standard equivalent complex phase steels and high-strength low-alloy steels (HSLA). From a vehicle weight perspective, the XPF range, with its unique nano-precipitation strengthened single-phase ferritic microstructure and its superior product characteristics, allows manufacturers to create parts that can be more than 15 percent lighter than those produced with equivalent advanced steel grades – even compared to HR CP800.
The improved stretch flangeability of XPF800, with an average Hole Expansion Capacity of 90%, enables geometric changes to a part’s design that increases stiffness while delivering mass reduction. When compared to HR CP800, the new hot-rolled XPF800 steel combines this higher stretch flangeability with higher tensile elongation. These product characteristics ultimately lead to reduced risk of edge shearing, allowing additional flanges and deep sections to be incorporated in the design to maintain, or even improve the end-product performance.
These factors all support automotive manufacturers to optimise their total cost of ownership (TCO). Not only does the formability of XPF800 enable light-weighting potential, but it also gives the opportunity to create new designs that help with parts consolidation and press shop yield. The characteristics of XPF, compared to CP800, create less material waste and less downtime of the production line when making complex parts.
Freek Schut, Tata Steel’s European Sales Director for Automotive, said: “The XPF family of steels is a major breakthrough in automotive structural materials technology. It addresses the known challenges regarding high-strength steels for demanding chassis applications. Its superior product characteristics, such as stretch flangeability and tensile elongation, give car manufacturers more design freedom and greater ability to improve total cost of ownership, through finding the right balance between cost, weight and performance benefits. Working alongside our proven body-in-white products such as MagiZinc®, Serica® and HyperForm®, the XPF range further demonstrates Tata Steel’s expertise to offer the lowest total cost of ownership in the chassis area.”
