For years carmakers have been cutting vehicle weight by stamping structural parts out of so-called tailored blanks.

These prepared sheets vary in thickness and may include areas with different alloys. When stamped into final shape, they put strength and other performance characteristics exactly where they’re needed in a part.

The idea is enjoying a resurgence today, thanks to advanced high-strength steels, says Gagan Tandon, director of product development for ArcelorMittal Tailored Blanks Americas. He says applications are growing for large and complex parts such as rails, pillars, door rings and other body structural components.
