Boron nitride. Boron nitride is a heat- and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN. It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice.
Boron will have a relatively greater effect on a section that can be fully hardened than on one which quenches only to, say, 50% martensite. As a practical matter, the effect of boron on hardenability is often denoted by the 'Boron Factor', the ratio of the ideal diameters of a boron steel to the same steel with no boron. Medium carbon steels should have boron factors in the range 2.0-2.5.
