High-Strength Steel for Cost Effective Weight Reduction 760207

Substitution of high-strength steels for low-carbon steels in automotive components to control spiraling weight increases in recent years is discussed. Material design interacting parameters are considered for efficient utilization of these materials. The economic justification for material substitution in terms of strength levels and grades are discussed in detail. Significant stamping experience in forming these materials for Lightweight Charger XL is presented in this paper. Examples of formed parts are shown and die modifications associated in forming some of the parts are also outlined.
