Abstract
Warm forming of Austenitic stainless steel has much attention due to usage of this material in various industries applications and at room temperature there is not much improvement in the formability of Austenitic steels. In the present investigation formability analysis of ASS 304 material (18.4% chromium, 8.1% Nickel) sheets are studied under warm forming by both theoretical and experimental results. The results show that the formability of the ASS 304 could be improved significantly at elevated temperatures. In this investigation deep drawn cups are drawn by considering various process parameter like constant punch speed, varying blank diameter, blank holding pressure and temperature of the blanks. Finite element analysis and experimental load displacement curves are studied to predict the formation of the process defects. The results shows reasonable agreement between the theoretical and experimental data curves which substantiate the finite element analysis.
