As automakers are challenged to improve safety and fuel economy, they continue to search for new materials to meet the higher performance demands of body structures. Working with its automotive partners, ArcelorMittal is responding to that challenge, adding to its family of advanced high strength steels (AHSS) for the auto industry.
With the development of GI Fortiform® 980, the limitations that body engineers had experienced when using second-generation higher strength steel grades for parts that play a role in energy absorption, or parts that were complex in shape, are eliminated.
“The new GI Fortiform® 980 range of AHSS for cold stamping combines superior formability and ductility at higher strengths that exceed the capabilities of the second-generation AHSS, thus opening up significant new opportunities for AHSS in body engineering,” said Hassan Ghassemi-Armaki, lead research engineer, Global Research and Development, East Chicago. “This is a crucial advantage as carmakers come under pressure to further lighten vehicles as a part of their strategy to improve fuel economy.”
“Because of its superior properties, GI Fortiform® 980 could help achieve weight savings of up to 20% compared to conventional AHSS while meeting increasingly stringent crash and safety requirements,” said Qaiser Khan, senior engineer, Global Research and Development, East Chicago. “This grade is suitable for use in many structural parts of the vehicle that are affected during impact, including front and rear rails.”
