D-segment cars cut weight by 25% in latest S-in motion® study

Scroll down to read article

A new S-in motion® study from ArcelorMittal has identified potential weight savings of up to 25 percent on the body-in-white of European D-segment vehicles by compared with recent models. The new study in the S-in motion® suite uses the latest advanced high strength steels (AHSS) from ArcelorMittal including Usibor® 2000 and Ductibor® 1000. Emerging grades from the Fortiform® range have also been considered.

The lightest S-in motion® solution reduced weight by 98 kilograms (25 percent) at a cost of less than €2 per kilogram saved

The D-segment S-in motion® study expands on a 2015 project which looked at the lightweighting potential of steel in mid-size sedans for the North American market. In the D-segment study, which uses European standards for structural performance, multiple options have been identified for each component of the vehicle structure including the body-in-white, closures, and hang-on parts. Both hot and cold stamping options are identified in many cases. All solutions are available to carmakers anywhere in the world thanks to ArcelorMittal’s global footprint and proximity to major carmakers.

Latest grades and coatings included in study

The steels tested in this S-in motion® study are cutting-edge – some of the new Fortiform® grades which are utilised in this project are still to go into full production, while Usibor® 2000 and Ductibor® 1000 have just been released. ArcelorMittal’s new grades in the Fortiform® family have proven perfect to meet the lightweighting challenge of S-in motion®. But in addition to its lightweighting potential, Fortiform® also offers high strength and excellent response to cold forming operations.

ArcelorMittal’s S-in motion® of the D-segment vehicle used new and emerging automotive grades

ArcelorMittal completed its offer of steel grades for hot-stamping with the release of Usibor® 2000 and Ductibor® 1000. While Usibor® 2000 provides unprecedented level of strength, Ductibor® 1000 combines high strength with excellent crash ductility. That makes it perfect for energy absorption applications.

As well as new automotive steel grades, ArcelorMittal is expanding its portfolio of automotive coatings. One of the latest is Jetgal® which was developed to protect very high strength cold rolled products such as Fortiform® and MartINsite®. These grades, coated with Jetgal®, are particularly useful for structural applications in the car underbody where higher strength is required. The galvanic corrosion protection provided by Jetgal® can be an asset for some OEMs in these applications.

ArcelorMittal’s complete offer includes automotive steels which can lightweight all parts of the vehicle

ArcelorMittal’s latest S-in motion® study again shows that advanced steels can be the solution to the lightweighting challenges carmakers face – and at a very cost-effective price.
