The prevention or minimization of erosion is an urgent need. The proper selection of the material and the adopting methods for controlling the factors influencing erosion are the commonly used techniques. Duplex Stainless Steel because of its good corrosion resistance and other properties becomes a common choice. To have an effective control over erosion we must understand the effect of each parameter over the rate of erosion. Air jet test rig was used to study the erosion behavior of Duplex Stainless steel of 2205 grade in a controlled environment. Erosion tests were carried out with varying angle of impact, flow velocity and mass flow rate under standard conditions using an air jet erosion rig made according to ASTM G76 standard. Examination of the results associated with various elements such as impact angles, mass flow rate and flow velocity. The results showed that the erosion rate was maximum at lower impact angles and decreases with higher impact angles and the erosion rate increase with an increase in velocity and decrease with the increase in mass flow rate
