Ferro Boron
Ferro boron is a type of ferroalloy that is made up of boron and iron, with the boron varying between 17.5% to 20%. Its CAS number is 11108–67-1.
Ferro boron can improve the quenching degree and mechanical behavior of steel and in high-quality alloy steel, boron takes the place of chromium, molybdenum and nickel, and do es not affect their mechanical behavior.
Ferroboron is stable under normal storage and handling conditions.
A key benefit of adding ferroboron to an alloy is that it can drastically increase the magnetic susceptibility of the end alloy, thereby making it suitable for the production of Nd-Fe-B magnets.
Another benefit is it can drastically increase the deep quench ability of the end alloy.
Ferro Boron Applications
- To improve the hardenability of C-Mn and low alloy steels
- Improvement of steel and nitrogen scavenging
- As low loss materials for NdFeB magnets
- In the production of low carbon cold working wire rod
