Research on ultra-high strength (fy>690 MPa) steel structural steel
Advances in steel production technology and processing techniques have significantly improved the strength and processing performance of steel structural steel. With the development of production and processing techniques, it is now possible to produce steel with a nominal yield strength of 2000 MPa.
The production processes for ultra-high-strength steelsteel and ordinary-strength steel differ, resulting in significant differences in their mechanical properties, including strength, ductility, toughness, and yield-to-tensile strength ratio. Therefore, changes in the material properties of ultra-high-strength steel structural steel inevitably lead to differences in the mechanical properties of ultra-high-strength steel components compared to ordinary steel components.
Mechanical properties of materials
Static tensile mechanical properties
To ensure that steel structural steel and their components have sufficient ductility and plastic deformation capacity, steel structure codes in many countries specify limits for the yield-to-tensile strength ratio and elongation after fracture of steel materials.
Material toughness
Currently, the main indicators of steel structural steel toughness are impact toughness and fracture toughness. The impact toughness indicator is the Charpy impact energy value Akv, which is usually obtained from impact tests on V-notch specimens.
