    • Abstract
  • The mechanisms of oxid scale growth and exfoliation of high temperature heat-absorbing surface of austenitic stainless steel tubes exposed to steam for supercritical and ultra-supercritical boilers were described. The influence factors of oxide scale growth and exfoliation of austenitic stainless steels were emphatically analyzed. They mainly included chromium content, grain size, steam parameters, oxygen content in the steam, running time of the unit and so on. Some suggestions to prevent oxide scale growth and exfoliation were put forward, which could provide reference for boiler design and operation.
