Tata Steel says the mix of strength and formability of its XPF800 hot-rolled steel 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 Tata claims the XPF range can create parts that are 15% lighter than those produced with equivalent advanced steel grades.
The company says 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.
A hot-dip galvanised range is also in development.
