Abstract: This work presents the effect on wear behavior of as received and carburized mild steel sample at different load like 75 N , 200 N , and 375 N and at different tempering temperature like 200 ⁰C , 250 ⁰C and 300 ⁰C.The mild steel sample was carburized at 950 ⁰C .The heat treatment after carburization has been acknowledge that at some instant it improving the various properties of mild steel.The mechanical properties and wear behavior of mild steel samples carburized at temperature of 950 ⁰C and tempered at different tempering temperature of 200 ⁰C , 250 ⁰C and 300 ⁰C have been studied and it is observed that the sample with heat treatment improves the hardness , tensile strength and wear resistance of mild steel.For this experiment firstly the mild steel samples are carburized at temperature 950 ⁰C than soaking for two hour and then it is tempered at different temperature range of 200 ⁰C , 250 ⁰C and 300 ⁰C for half an hour.After this the carburized and tempered mild steel samples are subjected for different kind of test such as abrasive wear test at different load like 75 N , 200 N and 375 N, Hardness test and Tensile test.The result of these experiment shows that the carburized and tempered process greatly improve the mechanical and wear properties like hardness , tensile strength and wear resistance and these properties increases with increase in tempering temperature.The aim of these experiments to examine the effects on mechanical and wear properties of the carburized and tempered at different temperature , mild steel samples.
