Abstract
Cast H-Series austenitic steels (HK, HP, and micro-alloyed HP) are used extensively in several industries for a broad range of high-temperature applications. The H-Series stainless steels have evolved over many years of alloy development by trial-and-error additions of alloying elements. Further improvements in the performance of these steels will be possible only through a detailed understanding of the composition-microstructure-property relationships. This paper highlights some of the progress made in understanding the relationship between precipitation and creep properties of these alloys through using a combination of thermodynamic modeling, microstructural characterization, and mechanical property measurements.
