In order to enhance driving range for battery-electric vehicles or decrease CO2 emissions for conventionally powered vehicles, automakers are continuously looking for ways to lighten the load on their vehicles. While equally significant, additional advantages like improved driving dynamics and increased load carrying capacity differ by vehicle mission and brand.
Weight reduction efforts usually target side closure structures doors-in-white. They may be produced using any material without damaging the current infrastructure because they are fastened onto the structure, which prevents them from interfering with the mainline in the body shop.
Because of this, automakers have the freedom to produce door frames out of any material that is consistent with their goals for weight reduction and overall business strategy.
Although doors still rule the market, aluminium doors have recently emerged as a lightweighting option in some markets, albeit at a significant price premium.
In order to provide the automakers with more lightweight, cost-effective steel door solutions that match or surpass their requirements, the steel industry launched a series of investigations.
The Global automotive structural lightweight door system market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The biggest mining and steel firm in the world, ArcelorMittal, showcased its innovative, incredibly lightweight automobile door options.
ArcelorMittal’s worldwide R&D automotive team has shown that a light weight and cost savings can be realised using the steels and technologies already in use without sacrificing safety and structural standards.
Since that weight savings in the automobile industry are often expressed in grammes, this is a sizable weight reduction for one automotive application.
This temporary fix makes use of Dual Phase steels like FF280DP for the outer panel and UHSS grades like MS 1500 and Usibor for structural components. These steels are already in use in production automobiles and are readily available.
