The lightweighting potential brought by advanced high strength steels (AHSS) was studied on automotive exterior panels. The dent resistance was selected as a measure to quantify the lightweighting since it is the most crucial for exterior panels. NEXMET® 440EX and 490EX, which possess both the surface quality and high strength, are evaluated and compared with BH210 and BH240. The denting analysis was conducted first on representative plates with different curvatures to simulate the dented areas on door outer, roof and hood panels. In addition, both 1% and 2% pre-strain and baking scenarios are considered for this plate, which represent the most common situations for exterior panels. The maximal dent load that the plates can sustain was calculated and compared for all those steel grades. Then the dent resistance analysis was conducted on a selected door outer panel. The minimum gauge required to meet the dent resistance performance was obtained. The potential to down-gauge the exterior panels using NEXMET® 440EX and 490EX is clearly revealed.
