5. Results and Discussion 5.1. Test results: effects of elevated temperatures

Table 2 shows the V-notch impact test result for SUS 304 specimens. The impact tests were performed by using pendulum-impact hammer with a velocity of 5.4 m/s. From the testing of 6 specimens, it is still difficult to show a coherent trend in impact energy. In addition to the influence of temperature, the imperfections in specimen fabrication also contribute to the non-linear results of the test. Particularly, specimen I-60-1 displayed an exceptionally low rupture energy.
