Webb13 juli 2024 · Toughness is not only influenced by temperature but also by the structural state of the material. Quenched and tempered steels and fine-grained structural steels, for example, are characterised by their special toughness. Compared to normalized steels, this remains unchanged even at lower temperatures.
