Description

The microstructure and properties of Q460C high strength steel were studied in this paper. The results show that the margin microstructure of the test steel Q460C is banded ferrite + pearlite. The internal microstructure is banded ferrite + pearlite + bainite, the grade of banded microstructure is 2.5. The tensile strength, yield strength, post-fracture elongation and Brinell hardness of Q460C steel are 620MPa, 502MPa, 22% and 175HBW10/3000 respectively. The impact energy of -40°C is above 50J, and a large number of equiaxed dimples are evenly distributed in the impact fracture. The conditional fatigue strength of test steel Q460C under 107 is 250MPa. (paper)
