Abstract

The paper presents experimental results concerning changes in strength and fracture toughness characteristics of Hardox-400 high-strength steel in brittle-to-ductile temperature range from -100 °C to +20 °C. It was shown that the values of strength properties increased linearly with the lowering of the temperature during the test. The changes in fracture toughness characteristics with temperature are more complex and they will be described by the exponential type function.
