This paper reports the influence of different chemical composition, austenitizing temperature, quenching rate and tempering temperature on the mechanical properties and microstructure of martensitic stainless-steel SS 410 grade. For calculating general material properties such as hardness and yield strength of SS 410 grade, JMatpro software is used. Analysis of SS 410 grade has been done for austenitizing temperature ranging from 9250C to 10100C followed by tempering whose temperature ranges from 2050C to 6050C.The proper practices of quenching and tempering should be performed ensuring the suitable microstructure of the steels. To get fully Martensite, quenching has to be done at least at 0.40C/s or more than that. The results also shows that composition of carbon has great effect on transition temperature Ms and Mf of martensitic stainless steel 410 grade as compared to chromium. Air cooling or oil quenching this type steels from austenite phase results in microstructure consists of mainly hard and brittle martensite, small amount of retained austenite. Subsequent tempering process reduces hardness and increases ductility and toughness.
