Abstract
Austenitic stainless steels are special grades of steels with improved corrosion resistance and oxidation resistance. In this work forming limit diagrams (FLDs) for Austenitic stainless steels of grades AISI 316 and 316L of thickness 1.25mm have been studied and their suitability for forming applications have been examined. FLDs were experimentally found using the hemispherical punch forming test. The micro structural aspects, tensile properties, formability parameters of the above mentioned steels were studied and compared. The fracture surfaces of the formed samples were viewed using the scanning electron microscope (SEM) and the SEM images were correlated with the fracture behavior and formability of the sheet metal. It was found that the formability of AISI 316L posses good drawability and stretchability.
