Due to their high strength, Usibor® steels are particularly suitable for anti-intrusion parts. By contrast, the ductility of Ductibor® opens the door to hot stamped BIW parts which are strongly deformed during a crash.
When utilised together in a laser welded blank (LWB), Usibor® and Ductibor® can be tailored to offer unique strength and ductility combinations. Together they achieve safer crash behaviour on critical applications at minimum weight.
A study of the body-in-white (BIW) for a mid-sized sedan has demonstrated the suitability of Usibor® 2000 and Ductibor® 1000 in crash applications. The study found that the use of these grades could significantly reduce the weight of the BIW when they were deployed in passive safety structural parts.
Using Usibor® in a direct hot stamping process is simple and cost-effective
Almost 85 percent of the PHS sold are finished with an aluminium-silicon (AlSi) coating. As well as reducing the risk of corrosion, these coatings allow hot stampers to utilise the most cost-effective and flexible hot stamping processes.
An LCA analyses the potential environmental burdens of a product or service during production, use, and end of life
ArcelorMittal’s internal sustainability experts have used the life cycle assessment (LCA) approach to assess the environmental performance of the new grades. The lighter weight of parts realised with Usibor® 2000 and Ductibor® 1000 more than offsets the slight increase in emissions from the hot stamping process.
