DESCRIPTION
By incorporating ferro vanadium into steel, its weldability is significantly improved. Ferrovanadium promotes the formation of fine-grained microstructures, which reduce the susceptibility to weld cracking and improve the overall integrity of welded joints.
Additionally, ferro vanadium contributes to the refinement of grain boundaries, which act as barriers to crack propagation during welding. This helps to prevent the formation of brittle zones and ensures the weld’s strength and toughness.
Furthermore, ferrovanadium’s presence in steel reduces the formation of harmful impurities during welding, such as nitrogen and oxygen. These impurities can lead to porosity, reduced strength, and corrosion susceptibility. By minimizing their formation, ferrovanadium enhances the quality and reliability of welded steel structures.
