ML15MnVB is a cold heading steel wire. The precise chemical composition of this wire provides a moderate strength and hardness foundation for the wire, improves the deoxidation effect of the steel, enhances the hardenability and toughness of the steel, makes it not easy to break under complex stress, and has good plasticity and toughness, ensuring reliability and safety under harsh working conditions. It is not only a material, but also a strong guarantee for you to achieve high-quality product manufacturing, bringing unlimited possibilities for your projects and business.
