Microalloying refers to adding small amounts (typically less than 0.1%) of elements such as niobium, vanadium, titanium, or boron to steel bars. These additions form fine precipitates or carbides during steel processing, which refine the grain size and improve mechanical properties. Microalloying enhances strength, toughness, and weldability without sacrificing ductility or machinabil... https://bit.ly/3KV51a1
