About Steel Alloy
Steel alloyed with a small percentage of boron, which provides high hardenability. Soft as delivered — excellent formability before hardened and superior resistance to wear after heat treatment. The addition of boron forms nitrides, reduces aging effects and has a positive effect on drawing. As it is an inhibitor of ferrite formation in solid solution, it effectively prevents longitudinal cracks on the surface.
*Please be aware that the Case® brand belongs to the CNH Industrial Group and that it has no association with Methal Agriculture.
