Low carbon alloys are low in cost and easily shapeable. Chemical composition of a material determines the mechanical properties. In this paper 16MnCr5, low alloy steel is surface treated via carburizing and carbonitriding in sealed quench furnace and quenched with oil. The effects of tensile deformation, strain rate behaviour and fracture characteristics were investigated by scanning electron microscope (SEM). A detailed investigation was done on case hardness how the surface treatment alters the hardness of the material from surface to core. The fracture of the specimen after surface treatment shows results with an intergranular fracture with projected burs on the fractured specimen. This paper investigates the fracture mechanism of surface treated material.
