Characterization of Creep-Tested Super 304H to Examine Metallurgical Lifing Options
Ultrasupercritical coal-fired steam power-plants have higher operating temperatures and pressures than traditional plants and require materials that have improved strength and corrosion resistance, particularly in superheater and reheater boiler tube sections. Researchers subjected samples of the advanced austenitic stainless steel Super 304H to high heat and pressure and conducted detailed analyses of cavities and microstructural […]
