Abstract: The alloy steel EN24 as a base metal before heat treatment has limited applications because of its low values of tensile properties. In order to enhanced its mechanical properties, hardness, its machinability up to such an extent that it can be used as: gears, connecting rods, swivel arms, transmission parts, machine tool parts, dies, cylinders, cropping blades , aero planes & aerospace systems the alloy steel EN24 have to be heat treated with different processes. The above problems of alloy steel En24 is improved in this project by applying three heat treatment processes i.e. stress relieving, normalizing and hardened & tempered for each specimens and testing each specimens for their tensile properties, chemical composition, hardness & microstructures. The graphs and their comparative analysis are done in the end.
Keywords: Chemical Composition, EN24, Hardness Testing, Heat Treatment, Mechanical Properties & Microstructure study.

Scope of the Article: Heat Transfer
