316 stainless steel is widely used in industrial applications due to its enhanced corrosion resistance, primarily attributed to its molybdenum content. While its performance in static environments is well-documented, its behavior under dynamic, high-velocity flow conditions—particularly in the presence of sulfuric acid at elevated temperatures—remains less understood. This study investigates the corrosion behavior of 316 stainless steel under jet impingement conditions, simulating real-world processing environments. Electrochemical techniques, including linear polarization, were employed to evaluate the stability of the passive film and quantify general corrosion rates across varying flow velocities and temperatures (40–60°C). The results provide critical insights into the material’s suitability for use in aggressive, high-flow acid service conditions and inform material selection for enhanced durability and performance.
