Abstract

mostly steel are heat treated under controlled sequence of heating and cooling to modify mechanical properties to meet desired requirements of engineering applications. The main objective of this study is to investigate the effect of different annealing temperature on the impact toughness of low carbon steel grade Fe-415D. Sample of steel was purchased from local market. The steel samples were heat treated (annealed) in electric muffle furnace at different temperature level and holding times and then cooled in furnace. The toughness properties of the heat treated and untreated samples were determined using impact testing machine. Results showed that toughness properties of steel can be changed and improved by annealing heat treatment process.
