This paper presents the results of the investigation on the effect of soaking time on mechanical properties (hardness, tensile strength and yield strength) of mild steel. The mild steel samples were subjected to annealing at 910°C at different soaking time of 20 minutes, 40 minutes, 60 minutes and 90 minutes respectively. Hardness test, tensile test and yield test were conducted to determine the properties of annealed mild steel with increasing soaking time. The hardness showed almost the same value and a sudden drop in value at 40 minutes soaking time but later increased in value from 60-90 minutes. While the tensile strength and yield strength showed a continuous increase in value with increasing soaking time. There was a linear relationship between tensile strength and yield strength of the material for different soaking time.
