Abstract:
The microstructure and fatigue properties of Q960 high strength steel were studied by optical microscope, conventional mechanical properties and fatigue tests. The results showed that the microstructure of Q960 high strength steel was tempered sorbite, the grain size grade 9, and the internal inclusions A1 and B1.5. The brinell hardness of Q960 high strength steel was 326.5HBW10/3000, the tensile strength more than 1000MPa, the impact energy 86.5J, which indicated good strength and toughness. In the case of high fatigue strength, the dispersion of fatigue life was low. The dispersion of fatigue life increased with the decrease of fatigue strength.
