Evaluation of Mechanical Properties of Medium Carbon Low Alloy Steels

Abstract

Medium carbon low alloy steel is being used in the forged condition in the automobile, aerospace and transport industry. Reliability of critical components made of EN Series is directly based on the fatigue strength of this steel, which in turn is dependent on forging process. A review of literature shows that substantial information is available relating to structure and mechanical properties of medium carbon low alloys forged steels. Some information is available regarding the evaluation of mechanical properties of steels. In the light of the above, the present investigation was taken up to study the effect of variables on the chemical composition of EN Steels. Mechanical properties such as UTS, percentage of elongation, Percentage of reduction (%RA) and hardness,of the alloy was assessed. The aim of the study is to evaluate the possibility of replacement of this steel with lower Ni content.
