High Performance Ferrite (HiperFer)–A New Alloy Family

Abstract:

The high performance ferritic (HiperFer) stainless steel, which is under development at the Institute of Microstructure and Properties of Materials (IEK-2) at Forschungszentrum Jülich GmbH in Germany, provides a unique combination of creep, thermomechanical fatigue, steam oxidation and wet corrosion resistance. The balanced property profile makes it a high potential candidate for highly flexible, future power technology equipment like conventional back-up power plants, concentrating solar power plants or “Power-2-X” conversion systems. This paper outlines the impact of chemical composition, heat and thermomechanical treatment on mechanical properties (tensile, creep, thermomechanical fatigue and Charpy impact strength) of these novel steels and their welds. An overview on the development status reached and the future development and application potentials will be outlined.
