The metallurgical advancements exhibited in creep strength enhanced ferritic (CSEF) steels have changed the dynamics of boiler design and operation by improving the fatigue life of thick-walled components and improving cycle efficiency by increasing operating temperatures. These advancements have a similar effect on the assessment of these materials. No longer can a serviceability evaluation be based on a general assumption of metallurgical properties. Instead, condition assessment protocols, examination methods, and flaw assessment approaches must reflect the metallurgical nuances of these high temperature alloy steels. This paper will provide guidance on new issues to be considered when developing a serviceability program.
