Corrosion Properties of F 82 H in Flowing High Temperature Pressurized Water

This work reports the effects of water flow and dissolved oxygen (DO) on corrosion behavior of reduced activation ferritic/martensitic steel, F82H. The corrosion tests were performed in high temperature pressurized water by using a test apparatus for rotated disk sample. All of specimens showed weight gains after static corrosion tests up to 500 h. However, the rotated disk showed weight losses except for test in the water with DO=8 ppm, and the weight loss was significant with lowering DO concentration.
