Explanation
Engineering structural steel with low carbon bainite structure at room temperature. Usually, the carbon content is less than 0.05%. When the carbon content is less than 0.03%, it is often called ultra low carbon bainitic steel steel (ULCBsteel). Its matrix structure is basically carbon free bainite plus a few evenly distributed Ma Ao islands, so its strength is significantly higher than that of ferrite-pearlite steel. Due to its low carbon content, it has good toughness and weldability. When higher strength is required, it is often strengthened by precipitation of microalloyed carbonitride or copper.
