This paper deals with the effect of sensitization on the metallurgical properties of austenitic stainlesssteel. Austenitic stainless have Nickel and Chromium as basic constituents. It has excellent corrosion resistance properties and very good weldability. Austenitic stainless steels have a tendency to form chromium depleted zones at the grain boundaries during welding and heat treatment, where chromium combines with available carbon in the vicinity of the grain boundaries, to produce an area depleted in chromium, and thus becomes susceptible to intergranular corrosion. Austenitic stainless steel during welding GTAWhave been investigated and concluded that variation in normalize temperature, time and heat input due to welding and heat treatment resulted in significant changes in the mechanical properties of the austenitic stainless steels and due to the effect of sensitization mechanical properties (yield strength, ultimate tensile strength, hardness,Corrosion resistance) of the material will be changed.
