<div>Influence of various parameters of final machining on stress corrosion cracking of austenitic stainless steel was investigated. Boiling magnesium chloride solution was used as a medium for exposure of samples to find out the susceptibility for corrosion cracking. Residual stresses, the roughness, hardness of the surface layers, feed and cutting speed were the main parameters which were noticed, and their effect was evaluated and compared. The density of cracks on the surface of the machined samples was obtained, as well as the depth of these cracks into the material, while their morphology was also monitored using SEM. Light microscopy was used to monitor the surface after machining (before the corrosion test). Subsequently, the hardness was measured. The machined surface was also analysed using electrochemical methods such as potentiodynamic measurements and electrochemical potentiokinetic reactivation tests for intercrystalline corrosion susceptibility.</div>
