Difficulties which occur in turbines as a result of exfoliation of high temperature oxide scales from superheaters, reheaters and steam piping have been discussed for the past 10-15 years in the literature. A number of investigators have studied the nature and growth of oxide coatings on low chrome steels as well as 300 series stainless steel. This work when reviewed and summarized indicates a consistent theory of scale development and mechanism of exfoliation. We will summarize the mechanism of scale exfoliation as it relates to means aimed at reducing the impact of the problem.
