Any~ replacements to - 1 portions of the system have been with a ' chromium-molybdenum alloy. Note (3): Erosion / corrosion has been identified - downstream 'of valves and orifices as well as opposite of. branch connections. Note (4): Erosion / corrosion of turbine blades. as well as slight erosion of.a low l pressure casing inlet ' have. been identified.
