Abstract: Forming limit diagrams (FLDs) are constructed to describe the strain rates at which a highly localized zone of thinning or necking becomes visible in the surface of sheet metal. Austenitic Stainless Steel 304 is used in nuclear industries specifically to make heat exchangers and different parts of core. The previous research carried out is focuses on the formability study of ASS 304 in deep drawing set-up but to study the entire formability history we need to construct FLD. In this investigation we plan to construct forming limit diagram at 1500c and punch speed of 30 and 50mm/min.In ASS, austenite will convert into some other microstructure either due to change in temperature or due to change in strain rate. So in the present investigation the effect of strain rate on formability studied at temperature 1500c
