Great Designs in Steel 2018 Presentations: A Closer Look at Lightweight Bumpers in Steels with Enhanced Strength
I-CAR · June 18, 2018
Summary
This article highlights a 2018 Great Designs in Steel presentation by Gestamp regarding the future of lightweight bumper systems. It discusses the development of next-generation bumper reinforcements utilizing 2,000 MPa press-hardened steel and crush boxes utilizing 1,200 MPa steel to reduce vehicle weight and improve crash performance.
What to do on the job
Identify the specific steel strength ratings of bumper reinforcements and crush boxes during blueprinting, as ultra-high-strength steels (1,200–2,000 MPa) require strict adherence to OEM non-repairability and replacement guidelines.
How to use it
Use this document to justify the complete replacement rather than repair of modern bumper reinforcements and crush boxes. When negotiating with insurers, reference the extremely high tensile strengths (up to 2,000 MPa) of these components to explain why heating, pulling, or straightening is structurally unsafe and strictly prohibited by OEMs.
