Abstract

The objective of this study is to determine the effect of heat treatment process such as annealing, normalizing and hardening on the mechanical properties of special grade steel known as cold rolled structural steels.The cold rolled structural steels are the medium carbon steels widely employed for making engineering components such as springs, gears, boiler plates, nuts and bolts, bearings, crankshafts, axles, pistons, valves and many other components. Such steels are frequently subjected to thermal and mechanical treatments in order to develop desired mechanical properties. Structural steels consist of a larger number of steels and hence cannot be described under single heading. These steelsmay be subjected to annealing, normalizing& hardening treatments to alter the mechanical properties. Specimens were prepared for different tests as per the standards.The experimental results give idea about the mechanical response of the material to the heat treatment processes. Through this the role of heat treatment on mechanical properties of the experimental steel is established. The following research is an empirical study which means it is derived from experiment and observation rather than theory. In all the tests 5 trials are performed and the average of three consistent values is considered as result output.
