HEP Metallurgy CSEF (P91) and Low Alloy Steels

HEP Series 3 of 5

This webinar will first provide a brief introduction to the steels commonly used in high-energy piping systems, and then provide a more in-depth review of the significant differences between traditional low-alloy steels, such as P11 and P22, and the more recently-introduced creep strength enhanced ferritic steels, such as P91, particularly with regard to manufacture, quality control, creep damage development, and creep damage detection. The implications of these differences for management of high-energy piping systems will be discussed.

Presenter Bio
Terry Totemeier


Dr. Totemeier has over twenty-five years of experience performing research, development, and failure analysis of materials used in power generation equipment, both fossil and nuclear, with a primary focus on the physical metallurgy, mechanical behavior, and oxidation/corrosion resistance of Fe-base and Ni-base alloys for high-temperature service. During his time working at the Idaho National Laboratory, Dr. Totemeier performed fundamental studies on processing-microstructure-property relationships in creep-strength enhanced ferritic (CSEF) steels such as Grade 91.  This fundamental background was supplemented with extensive real-world experience while working at the Alstom Power
