Weight Reduction of Automobile Bumper Systems 760012

Weight reductions in automobile bumper systems were achieved by means of a three phase program:
  1. 1.
    Reduction of bumper reinforcement gauge by use of work hardening renitrogenized steel.
  2. 2.
    Reduction of bumper face bar gauge by use of high formability, high yield strength, inclusion shape control steel.
  3. 3.
    Design changes to minimize or eliminate bumper reinforcements.
The weight reductions were achieved without reducing the impact strength of the bumper systems.
