The first step in meeting the new challenge was to take advantage of advanced engineering techniques to create lighter steel, including new hot-stamping processes and laser-welded blanks, according to ArcelorMittal. While the new products cost more, customers would use less, according to Aranha. That cuts the weight by about 20 percent for roughly the same cost. The new products are already available for pickup trucks.
Steel is striking back, in the form of there not being enough aluminum chassis from supplier Metalsa in order to keep up with standard F150 production. The lack of chassis is delaying all of production, which I'm sure is contributing to a delay in Raptor production!
