Ferro Boron
Alloy of boron and iron.
According to carbon content, boro-iron (boron content: 5-25%) can be divided into low carbon (C≤0.05% ~ 0.1%,9% ~ 25%B) and medium carbon (C≤2.5%,4% ~ 19%B). Iron boron is a strong deoxidizer and boron addition agent in steelmaking. The greatest role of boron in steel is that only a very small amount of it can significantly improve the hardenability and replace a large number of alloying elements. In addition, it can also improve mechanical properties, cold deformation properties, welding properties and high temperature properties.
