SOME ASPECTS OF FORMABILITY OF ASS 304 UNDER WARM CONDITIONS
Keywords:
Warm forming, Deep drawing, ASS-304 , MicrohardnessAbstract
In this study Austenitic stainless steel 304 (ASS-304) are deep drawn under warm conditions and by using 20Ton hydraulic press, there is an increase in formability as the temperature increases. Experiments are conducted to study the thickness distribution at various temperatures and also analyzed the safe blank diameter that can be drawn without fracture. Vickers microhardness test is performed on cut section of deep drawn molded cup samples at neck, base and wall region for different blank diameters and variable temperature. It is observed that microhardness depends considerably in the drawn cup depending upon the region and the temperature at which the material is drawn.
