The aim of this work is to study Sensitization Behavior of AISI 304L stainless steel with varying normalization time. Yield strength, Ultimate tensile strength, percentage of elongation and toughness across the weld has been reported. The tensile and impact properties of the welded joints have been evaluated using Electro mechanical controlled Universal Testing Machine and Pendulum type Impact Testing Machine. The microstructures of the sensitized samples, are analyzed using an optical microscopy. From this investigation, the following important results are derived: The yield strength, tensile strength, and impact toughness of austenitic stainless steel remarkably decreased as the temperature was increased. The microstructures of sensitized samples indicate that carbide precipitation increases with increasing time and normalization temperature; elements treated at 850°C with a 2 h holding time and then cooled in air are the most sensitized.
