Warm forming of high strength sheet metal alloys are in great demand and its application has importance in defense and nuclear industries. In the present investigation the austenitic stainless steel (ASS)-304 blanks are deep drawn under warm conditions using 20Ton hydraulic press and observed that at lower punch speed when the cup is drawn at elevated temperatures the formability is improved. Numbers of deep draw experiments are conducted under warm conditions to study the microstructure at elevated temperatures for punch corner region cups at variable speeds. In this investigation, changes in the microstructure are observed for deep drawn cups at ambient and elevated temperatures
