Influence of the composition of structural steels on notch toughness translation temperature

Due to the numerous applications of structural steels, the different mechanical properties are required. The most important required mechanical properties are the high yield strength, high strength and high impact energy at 20 °C and the lowest possible toughness transition temperature. In this paper, the effect of testing temperature on the impact energy on three different structural steels was researched. The testing was done on structural steels S355J0, P265GH and 13CrMo4-5 at following temperatures 20 oC, -10 oC and -40 oC. To determine the applicability of specific types of structural steels, the dependence curves of impact energy and testing temperatures were used.
