Heat treatment is process to modify the mechanical, physical and somewhat chemical properties by heating
or cooling at desired temperature. Carbon is absorbed in steel with help of coal material according to proper heating
and tempering time and temperature in carburizing process. The mild steel specimens are made from standard sample
size according to perform different test. The mild steel samples are carburized at 9000C temperature and socking time up
to 120 min. Then quenching in oil bath and tempered at different temperature like 2000C, 2500C, 3000C for ninety
minutes .These standard specimens perform under different test like 50N, 150N, and 250N load for wear test. Mechanical
test performed on their standard dimension and size according to hardness, tensile and toughness test. During this test
carburizing process improve the wear, hardness, tensile strength value and compromise in toughness at higher
tempering process in mild steel material.
