The alloy steels are extensively used in every industry ranging from household utensils to the aerospace industry. This research work mainly focuses on the evaluation of the mechanical properties of martensitic stainless steel SS410 & SS420 materials subjected to tempering heat treatment process by various levels of temperature. Most of the martensitic steel is subjected to the tempering process to vary the mechanical properties like ductility & toughness is required for most of the applications varying from household utensils to the aerospace industry. Steel properties can vary to a great extent with even a small change in its chemical composition and temperature. The martensitic stainless steels SS410 & SS420 are subject to microstructure examination and the mechanical properties like hardness, tensile, and impact strength are evaluated for each specimen. The results are then compared with the untreated and heat-treated martensitic stainless steels SS410 & SS420 for the change in its microstructure and mechanical propertie
