Oil and gas industry have employed Corrosion Resistant Alloys (CRA) in highly corrosive environments for a sustained production capacity and longer service life. These materials are regarded to have high resistance to corrosion, however, a prominent issue that can occur in O&G production is the potential of erosion along material surface. In this study, ASTM G76 standard was used as basis to generate high nickel alloy erosion database. The materials used in this study include N06255, N08535 and N07718 with respective nickel content of 48.5, 31.4 and 48 %wt. An Air-Jet Erosion Tester was utilized with Alumina Oxide as erodent for this study, in which the feedrate varied between 1 – 6 g/min with a 1g/min step, impingement velocity ranging between 30 - 110 m/s and a varying impingement angle (15° - 90°) with 15° step bringing the total number of runs in excess of 100. The erosional behavior of materials N06255, N08535 and N07718 were studied and the resulting steady state erosion rate (SSER) for each was determined. The tested materials were ranked based on SSER from lowest to highest metal loss per time as follows N06255, N8535 and N07718 which could be attributed to difference in molybdenum and nickel content.
