Abstract:
Background and Objective: The properties of SS316L stainless steel plate are significant due the wide range of usage of the stated material. It can be governed by the chemical composition and microstructure. This study deals with the investigation of major parameters used for predicting the grain size of austenitic stainless steel SS316L at different temperature range. The major grain growth variables such as; kinetic exponent and grain growth rate constant had been studied to interpret the mechanism in the samples with different heat treatment settings. Materials and Methods: The material investigated was austenitic stainless steel SS316 L. Samples were isothermally held at various temperatures and holding time. Results: Based on the results, the kinetic rates were plotted by using the Arrhenius equation to predict the grain size. Using this method the estimated grain size shows an acceptable error percentage up to 12.5% for temperature at 1100°C and for the temperature of 1200°C or above. Conclusion: it is concluded the grain growth will be abnormal at higher temperature range, the precipitate that occurs at the grain boundary layer can be implemented for a modified Arrhenius equation.
