Sažetak
The high temperature properties of AISI 304 stainless steel were studied. Basic data about the employed experimental equipment, testing procedures, and specimen geometry were given. The experimental setup was used to obtain stress-strain diagrams from tensile tests at room temperature as well as several elevated temperatures. Furthermore, the specimens were subjected to short-time creep tests at various temperatures. Stress levels for creep testing were established as a percentage of yield stress. The results indicate that at lowered temperatures and lower stress levels, AISI 304 stainless steel can be used as a sufficiently creep resistant material. as well as several elevated temperatures. Furthermore, specimens are subjected to short-time creep tests at various temperatures. Stress levels for creep testing are established as a percentage of yield stress. Based on obtained results, constitutive model is derived. Some conclusions about material short-time creep resistance are also noted.elevated temperatures.
