Tensile and Hardness Tests on Steel Specimen

Abstract

Steel specimens were subjected to both tensile tests and hardness tests. The tests were carried out Mild steel .The specimens were tested under various conditions. The maximum hardness was for the specimen quenched with water, however the tensile strength of that particular specimen was the minimum. While the tensile strength was highest for slow cooling and furnace cooling .However the hardness for slow cooling was the least. While furnace cooling was comparatively higher. The other specimens had varied tensile strength and hardness and it was not possible to map a relationship of the two. The motivation for this work has been that the students involved have recently been exposed to material strength and its variation with temperature.
