Creep Strength Enhanced Ferritic (CSEF) Steels, such as Grades 91 and 92, are finding increased application in power plants because of their excellent strength at high temperature. However, to achieve that strength these alloys must be carefully produced to tight chemical compositional specifications and heat treatment requirements.This course will provide an introduction to these steels and will explain how the properties of CSEF components can be compromised, how they may be assessed, and what that means for serviceability. This will include discussion of the implication of various fabrication processes, such as welding. Developing a life management plan for different types of components fabricated from CSEF steels will be explored, along with destructive and nondestructive examination approaches to verify serviceability.
This course should prove valuable to power plant engineers who are tasked with purchasing, designing, fabricating, operating, and managing components fabricated from CSEF steels, such as Grade 91/92.
The course will cover the following topics:
1. Introduction to CSEF steels
2. Metallurgical basics
3. Heat treatment
5. Elevated temperature behavior
6. Life management
7. Common industry issues
8. Future trends in CSEF steels
1. Facility tour
a. Optical metallography showing typical/bad microstructure
b. Hardness testing
c. Examples of creep damage
Ian Perrin, Ph.D. Vice President of Fossil Plant Services, earned his doctorate in Mechanical Engineering from the University of Manchester in the United Kingdom. His background includes over 20 years of experience in engineering for fossil power plant components, including the application of finite element analysis, reference stress, fracture mechanics and damage mechanics. Ian is a leading expert on the inelastic behavior of metals at high temperatures. His extensive knowledge of mechanical engineering and materials help Structural Integrity bring the most advanced science-based solutions to the energy industry’s most challenging integrity issues.
Dr. Totemeier has over twenty years of experience performing research, development, and failure analysis of materials used in power generation equipment, both fossil and nuclear.
