Abstract

An investigation was carried out to determine the effect of soaking time during sensitization on the Mechanical properties of Austenitic stainless steels [1]. The selected samples of AISI 316 and AISI 304 were cut into several pieces so that different amount of sensitization was introduced into the different pieces. To induce sensitization, the samples were heated and soaked at 750°C for different time intervals such as 30 minutes, 60 minutes, 180minutes, 300 minutes and 600 minutes followed by water quenching. The resultant samples were tested for Tensile strength, Micro hardness and Macro hardness. It was concluded from the results obtained that the macro and micro hardness of AISI 316 and AISI 304 decreases with increase in soaking time at a constant soaking temperature., However, the macro hardness of AISI 304 decreases more than AISI 316 with increase in soaking time at specified soaking temperature. It was similarly concluded that the tensile strengths AISI 316 and AISI 304 decreases with increase in soaking time at a constant soaking temperature.
