Effect of aging temperatures on the microstructural stability and mechanical properties of Super304H steel

Journal of Materials Research and Technology
Aging tests at 650 °C and 700 °C for up to 5000 h were performed on Super304H steel tubes. The microstructural evolution during aging was observed by optical microscopy (OM) and scanning electron microscopy (SEM).
