In this paper, the method rotating the suspended metal samples were used to simulate water granulation sulfur solidification process. In the experiment, the corrosion rules of 316L and 20# Steel due to the change of temperature and position were researched. Corrosion weight loss, Scanning electron microscopy,Energy dispersive spectrometer were used to find the corrosion rules. The experiment results show that: 316L was slightly corroded and the corrosion rate was between 0.0008mm/a and 0.0070mm/a. The corrosion products on the surface of the material were little, and the main component is Fe2O3. 20# Steel was severely corroded in the process and the weight loss corrosion rate far beyond the sour gas field corrosion control standard 0.075mm/a. At least two membranes of corrosion products were formed at the surface of metal samples, and the main components are Fe2O3 and FeS. High temperature and erosion will accelerate the corrosion rate. The simulation results show that when it comes to the granulation of sulfur particles in the industrial field, 316L can be applied for long period while the equipment and pipelines manufactured with 20 # steel should be replaced as soon as possible and monitored regularly to ensure the safety of the production apparatus.
