The erosive wear experiments on materials of Q235, Cr12Mov, ZG310-570 and Q345A commonly used for centrifuge transflux parts were conducted with sandblasting machine, and their erosive wear characteristics were studied. Results show that the erosive wear resistance increases with the hardness of the material while the mass loss rate decreases. On the same experiment condition, the erosive wear resistance of materials from high to low is as below: Q345A, ZG310-570, Cr12Mov and Q235A. The mass loss rate of the experimental materials firstly increases and then decreases with the increase of impact angle, and it is up to the maximum at the impact angle of 30°. The erosive wear mechanism of experiment materials mainly appears micro cutting under the condition of low angle impact, while exhibits repeated plastic deformation resulting in fatigue fracture under the condition of high angle impact.
