In the present investigation, the 304 austenitic stainless steel has been strained up to 0% and 15% reduction in thickness, and analysis has been done with the help of X-ray diffraction (XRD) and microstructure. In 304 austenitic stainless steel (ASS) the microstructure through optical as well as scanning electron microscope 9SEM) has been studied at various thermal aging temperatures with and without strained at 0% and 15%. X-Ray diffraction results show that as stacking fault energy is greater with an increase in straining from 0% to 15%, 304 ASS seems to be deformed more quickly, resulting in a fast conversion to strain induced martensite from austenite. The XRD data also show that a higher percentage of martensite was produced. Microstructure results indicated that due to straining and high temperature heat treatment of 950°C-1000°C, small refined grains of new austenite formed which became the main reason for high strength and ductility. However other side shows that at a common temperature of 850°C-900°C, according to a microstructural study, the martensitic areas are an ideal source for increasing sensitization.
