Study Shows High-Strength Steel Most

Looks like High-Strength Steel may still be a strong option for new vehicle construction!

Study Shows High-Strength Steel Most Cost-Effective for Light weighting The Steel Market Development Institute is touting a new government study that shows advanced high-strength steel is the most affordable material for the reduction of mass in automobiles.

A new National Highway Traffic Safety Administration (NHTSA) report entitled Mass Reduction for Light-Duty Vehicles for Model Years 2017-2025 prepared by EDAG, Inc., George Washington University and Electricore, Inc. examined mid-size body, chassis and interior vehicle systems and determined that basic lightweighting costs $0.46 per pound of weight saved ($1.02 per kilogram) using advanced high-strength steels (AHSS), compared to $1.55 per pound ($3.41 per kilogram) using aluminum.

“Cost models have traditionally associated a significant cost penalty with alternative materials and this NHTSA report confirms this while demonstrating advanced high-strength steels provide significant mass reduction at the lowest possible cost,” Lawrence W. Kavanagh, president, Steel Market Development Institute, a business unit of the American Iron and Steel Institute, said. “This is significant, as automakers have the challenging task of developing affordable vehicles that meet new and tightening regulations.”

In addition to its cost advantage, steel’s crash performance was also confirmed in this report. George Washington University verified the excellent crash performance of the lightweight vehicle design in simulated New Car Assessment Program, Frontal, Lateral Moving Deformable Barrier, and Lateral Pole tests, along with the International Institute for Highway Safety’s Roof, and Frontal Offset tests.
