DEVELOPMENT AND USE OF VANADIUM IN MICROALLOYED REINFORCING BAR-ADVANTAGES OF HIGH-STRENGTH-STEEL

The use of reinforcing steel and its consumption per capita a year in some European countries are introduced. The application conditions of reinforcing steels as structure materials and their advantages as reinforcement used in concrete are also described. The production routs of reinforcing steel and its performance characteristics such as yield strength, ductility, weldability and fatigue etc. are stated in detail. Reinforcing steel using vanadium as microalloying element has advantages and characteristics in many aspects such as economy, metallurgy and so on.
