Study of the Effects of High Temperatures on the Engineering Properties of Steel 42CrMo4

The paper presents and analyzes the experimental results of the effect of elevated temperatures on the engineering properties of steel 42CrMo4. Experimental data relating to the mechanical properties of the material, the creep resistance as well as Charpy impact energy. Temperature dependence of the mentioned properties is also shown. Some of creep curves were simulated using rheological models and an analytical equation. Finally, an assessment of fracture toughness was made that was based on experimentally determined Charpy impact energy. Based on the obtained results it is visible that the tensile strength (617 MPa) and yield strength (415 MPa) have the highest value at the room temperature while at the temperature of 7000C (973K) these values significantly decrease. This steel can be considered resistant to creep at 4000C (673K), but at higher temperatures this steel can be subjected to low levels of stress in a shorter time.
