... and potassium chloride. As the steam expands through the turbine, the solubility of the corrosive chemicals decreases. When the solubility limit is reached the chemicals precipitate into droplets of concentrated solutions which are in equilibrium with the steam. Chemicals such as sodium hydroxide are in a class...

... of mixed salt present, which is stabilized by a high SO 3 pressure. The equilibrium PSO 3 /PSO 2 ratio increases with decreasing temperature, and it is generally accepted that this accounts for the observed high rates of corrosion at low temperatures. The rate of attack can be as great as that for HTHC...

These are ductile fracture, brittle fracture, high-cycle (ordinary) fatigue, low-cycle (plastic) fatigue, melting, and chemical dissolution. Hydrogen embrittlement is an example of a hybrid...
