| Description: The family of MartINsite® steels extends ArcelorMittal's range of Ultra High Strength Steels (UHSS). These steels allow the realization of lightweight structural elements by a forming method such as roll forming. To achieve maximum weight reduction while maintaining a very good anti-intrusion during the crash properties, some parts require the use of UHSS, such as the sills and door reinforcements, have simple shapes, and therefore the steel is slightly deformed. For this reason, ArcelorMittal has complemented its offer with the family of MartINsite® steels with very high yield strength delivery and interesting properties of bending deformation and a very good formability of the cut edges. Application: Thanks to their excellent mechanical properties, these grades are particularly suitable for automotive safety parts for shock resistance. Typical parts are shown in the figure below: - Front and rear bumper beams
- Door beam
- Side Sill Reinforcement
- Roof cross member
