Life Management Issues for Creep Strength Enhanced Ferritic Steels
A summary of in-service experience with Grade 91 steel will be presented. It is apparent that the advantages offered by creep strengthened ferritic steels, such as Grade 91, can only be realized with careful control of composition and fabrication methods. Appropriate quality assurance checks must be performed to ensure that properties meet requirements. Where these tests indicate that properties are marginal or below expected alues, follow up programs must be carried out to underpin analysis of long term performance. Because of concerns over accelerated creep damage development in weld HAZs, there are significant benefits to using advanced NDE techniques to identify and characterize defects.
