An Analysis of Hand Tool Material Used for Agriculture Work in Rural India

The heat treatment and carburization has been acknowledged by some means of improving the various properties of metals and alloys. In the present investigation the mechanical and wear behaviours of hand tool material (mild steel) carburized at different temperature range of 890, 920 and 950°C have been studied and it is found that the simple heat treatment greatly improves the hardness, and wear resistance of the hand tool. The aim has been to examine the effects of these different carburization temperatures and conditions on the mechanical and wear properties of the carburized hand tools. For above purpose firstly the hand tool material is carburized under the different temperature range are subjected for different kind of test such as abrasive wear test, hardness test. The results of these experiment shows that the process of carburization greatly improves the mechanical and wear properties and these properties increases with increase in the carburization temperature The experimental results also shows that the mild steels carburized under different temperature range as stated above, with in which the mild steels carburized at the temperature of 950°C gives the best results for the different kinds of mechanical and wear properties because at this temperature it gives highest hardness and wear resistance, so it must be preferred for the required applications.
