High-strength nickel free austenitic stainless steel material as a light-weight substitute for commercial automotive deep drawn steel has been studied with an automotive bumper as an example. The stainless steel gave a weight saving as high as 50% at the same cost that of deep drawn steels. The study examines the techno-economic merits of value engineering automotive material. The bumper made from stainless steel stamping was reduced in thickness to 1.2 mm from 2.5 mm of conventional Extra Deep Draw (EDD) grade steel. Forming behavior of the stainless steel bumper was theoretically simulated and was found to match with experimental observation. The Forming Limit Diagram (FLD) behavior of the stainless steel material shows superior formability. Typical static and impact load cases based on functional requirements of the bumper was simulated, and the light weight stainless steel bumper was found to perform better than the existing EDD bumper. The bumpers made qualified the vibration test requirement.
