Tensile And Formability Studies on AISI310 Austenitic Stainless Steel

Abstract

Stainless steel is an alloy of iron, chromium, and, occasionally, nickel and other metals that resists corrosion. Metal is made into thin, flat pieces through an industrial process called sheet metal. One of the fundamental shapes used in metalworking, it can be cut and bent into many other shapes. Metal sheet is used to create a vast array of common items. The aim of the current work is to examine the 310 austenitic stainless steel’s formability at room temperature with different strain rates (i.e 0.1&0.01mm/s). The study’s outcomes were achieved through the utilization of the Nakazima test during stretch forming. Before performing formability test, The mechanical properties of a high-strength stainless steel AISI 310 were examined by conducting tensile tests at room temperature with 0.1,0.01mm/s strain rates. The failure modes, stress-strain curves of all the test specimens were obtained and analyzed. In the current experiment, the stretch forming of different shaped metal was tested in servo electric hot forming machine with different strain rates i.e, (0.1,0.01) at room temperature and plotted forming limit diagrams based on the results. Then simulations of the experiments were performed in LS-dyna software and compared with the practical experiment results.
